Sell-Through Rate (STR) is the single most useful number a vape retailer can track. It tells you, in plain percentage terms, how much of the inventory you brought in actually sold — and how much is sitting on your shelf consuming working capital. This guide goes beyond the definition: it gives you the category-specific benchmarks that separate healthy inventory from dead stock, the warning signs that a SKU is heading in the wrong direction, and a practical system for using STR data to make better buying decisions before problems compound.
Units Sold ÷ (Units Sold + Units Remaining) × 100Run this over a 30-day window for each SKU. A result of 80% means you sold 80% of what you stocked. 20% is still sitting on the shelf.
Part 1: STR Benchmarks by Category
Not all product categories turn at the same rate. Applying a single STR benchmark across your entire inventory will cause you to misread both your best performers and your problem products. Use these category-specific targets as your baseline:
| Category | Healthy STR (30-day) | Concern Threshold | Why It Differs |
|---|---|---|---|
|
Disposable vapes (Lost Mary, DOJO, ALLO, Geek Bar) |
75–95% | Below 60% | High-frequency repeat purchase. Customers come back weekly or bi-weekly. Low STR on a disposable SKU usually means the flavour is wrong, not the brand. |
|
Closed pod systems (STLTH, RELX, Level X) |
60–80% | Below 45% | Pods are purchased slightly less frequently than disposables but generate loyal repeat customers. STR varies more by flavour profile than by brand. |
|
Open pod systems / kits (Vaporesso, Uwell, RELX) |
40–65% | Below 30% | Hardware is a considered purchase — customers research before buying. Lower turnover is normal. A kit sitting at 35% STR is not necessarily a zombie; check whether pod refill sales from the same brand are healthy. |
|
Salt nic e-liquid (KAPOW SALT, SUAVAE, ALLO E-Liquid) |
55–75% | Below 40% | Purchased by open pod system users — a smaller segment than disposable buyers. Healthy STR depends heavily on whether the flavour profile matches what your pod system customers want. |
|
Freebase e-liquid (Flavour Beast, LEMON DROP) |
45–65% | Below 35% | Sub-ohm buyers are a smaller, more price-sensitive segment. Wide flavour ranges with many low-volume SKUs will drag your category average down. Track individual flavours, not just the brand. |
|
Accessories (coils, batteries, cases) |
30–55% | Below 20% | Accessories are add-on purchases, not destination purchases. Lower STR is acceptable as long as margin per unit is healthy and the accessory supports an active device category in your store. |
Part 2: Low STR Warning Signs by Category
A SKU crossing below its concern threshold is a signal, not a sentence. The right response depends on why STR is low — which varies significantly by category. Apply a simple rule before acting: one month below threshold means monitor; two consecutive months below threshold means intervene. A single bad month is noise. Two consecutive months is a pattern.
Disposables: Flavour Problem, Not Brand Problem
If a disposable SKU from a strong brand like Lost Mary or DOJO shows STR below 60%, the issue is almost always the flavour, not the brand. Before discontinuing the SKU, pull the STR for every flavour from that brand side by side. If your fruit and ice SKUs are running at 85–90% and one dessert profile is sitting at 40%, the brand is healthy — that specific flavour is not right for your customer base. Stop reordering that flavour, replace it with a proven profile, and do not let one underperformer taint your read on the brand.
The other question to ask: is this a seasonal trough or a structural failure? A tropical ice flavour that drops from 88% STR in August to 55% STR in November is behaving exactly as expected — it will recover in spring. A flavour that has been below 50% for three consecutive months regardless of season is a genuine problem. Track STR month-over-month before making discontinuation calls, not on a single data point.
Pod Systems: Evaluate the Kit-Pod Relationship Together
Low STR on a pod kit does not always mean the product is failing. If STLTH pods are moving at 75% STR but the STLTH device itself is sitting at 35%, that is a healthy result — it means you have an established pod customer base that already owns the hardware. Customers buy pods repeatedly; they only buy the device once. Evaluating device STR in isolation will consistently make your hardware look like a problem when it is not.
The correct diagnostic is to look at the kit-pod pair together. If pod STR is strong and device STR is low, your pod system category is healthy — keep stocking pods at current or increased quantities, and carry only 2–3 devices on the shelf as entry-point product for new customers. If both pod STR and device STR are weak, that is the signal to reassess the brand's fit with your customer base. The right response in that scenario is to run down pod inventory, stop reordering devices, and redirect budget to a pod system brand that is already performing in your store.
E-Liquid: Manage by Flavour SKU, Not by Brand
Freebase and salt nic e-liquid brands often carry 20–40+ flavour SKUs. A brand average STR of 50% can mask a situation where 5 flavours are turning at 90% and 15 flavours are sitting at 15%. If you are evaluating e-liquid performance at the brand level, you will consistently over-buy slow movers and under-buy your actual bestsellers.
Pull STR by individual flavour, and apply a simple range management rule: for any e-liquid brand, stock only the flavours that have demonstrated at least 45% STR over two consecutive 30-day periods. For most stores, this means carrying 4–8 flavour SKUs per brand, not the full catalogue. A tighter range with high-velocity SKUs will always outperform a wide range with mixed performance — you free up shelf space, reduce dead stock risk, and make the buying decision easier for the customer at the same time.
The practical benchmark: if you are carrying more than 10 flavour SKUs from a single e-liquid brand and your overall category STR is below 50%, your range is almost certainly too wide. Start cutting from the bottom of your STR sort, not from the top.
Part 3: Using STR to Adjust Order Frequency and Quantity
STR data should drive two buying decisions: when to reorder, and how much to order. Most retailers get one of these right and miss the other.
| STR Result | Reorder Timing | Order Quantity Adjustment |
|---|---|---|
| Above benchmark (e.g. disposable at 90%+) | Reorder when 30% stock remains. Calculate days of stock: Units Remaining ÷ (Units Sold ÷ 30). Reorder if below 10 days. |
Increase by 20–30% on next order cycle. This SKU is underserved — you are probably losing sales to stockouts. |
| Within benchmark range | Reorder at 25–30% remaining stock. | Maintain current quantity. Recheck STR in 30 days for trend direction. |
| Approaching concern threshold | Do not reorder until current stock is below 20%. Run existing inventory down first. | Reduce next order by 40–50%. One more cycle at reduced quantity to confirm the trend before cutting entirely. |
| Below concern threshold for 2+ cycles | Do not reorder. Move to clearance protocol (see Part 4). | Zero. Reallocate buying budget to star SKUs in the same category. |
8 ÷ 20 = 40% — permanently below the 75% healthy benchmark for disposables, not because the product is failing, but because your order size is misaligned with your actual velocity. The fix is not to read your STR data differently. It is to work with a distributor who lets you order 8 units — or 10, or 12 — without a minimum. When your order quantity matches your velocity, your STR becomes a reliable signal instead of a distorted one.
Part 4: Clearance Strategies for Low-STR Inventory
Once a SKU is confirmed as dead stock — below its concern threshold for two or more consecutive 30-day periods — the goal shifts from selling at full margin to recovering capital as quickly as possible. Three approaches in order of preference:
Bundle With Star SKUs
Pair a slow-moving flavour with a bestselling SKU from the same brand at a modest discount. A customer buying a Lost Mary Blue Razz Ice 10-pack is a natural candidate for a "try something new" bundle — add a slow-moving dessert flavour at $2 off the combined price. At a $2 discount on a unit that cost you $8 wholesale, you are clearing dead stock at roughly 75% of full margin rather than leaving it on the shelf at 0% velocity.
Set a 2-week window for any bundle promotion. If the bundle has not moved in two weeks at $2 off, move to $3 off for one more week. If it still has not moved, the flavour is genuinely wrong for your customer base and no bundle structure will fix it — move to promotional pricing at the counter.
Promotional Pricing at the Counter
Counter placement with a clearly marked discount is the highest-visibility clearance position in a vape store without disrupting your main display. Place low-STR SKUs in a basket or small display at the register, clearly marked with a percentage discount — start at 15–20% off for a defined 2-week window.
Apply a decision rule at each stage: if the SKU does not move in 2 weeks at 20% off, escalate to 30% off for one week. If it still has not sold, escalate to 40% off and set a hard deadline — "everything in this basket clears by Friday." At 40% off you are likely selling below your original margin target, but you are recovering cash and shelf space, both of which are worth more than holding out for full margin on a SKU that is not moving. Product that never sells returns zero — discounted product recovers something.
Supplier Exchange
Some distributors will accept an exchange of unsold inventory for credit toward a new order, particularly if the product is recent, unopened, and correctly stamped. This is not a guaranteed option, but it is always worth raising with your wholesale account manager before writing off dead stock entirely.
When raising this conversation, be specific: provide the SKU, quantity, purchase date, and current stock level. Frame it as a product-fit issue, not a complaint — "this flavour profile isn't matching our customer base, and we'd like to exchange for X which we know moves well." A distributor you order from regularly has a direct financial interest in your store's success and inventory health. One you order from sporadically does not. This is one of the underappreciated advantages of a consistent wholesale relationship: access to practical flexibility that a transactional relationship does not provide.
Part 5: Matching Your Order Size to Your Velocity
The logic of STR-driven buying only works if your order quantities can reflect your actual velocity data. If your distributor requires a $10,000 minimum order per brand, you will over-buy relative to demand on every order — and your STR will be structurally suppressed regardless of how well you read the data.
Arctic Distributions operates with no minimum order quantity, which means your order can be exactly sized to what your STR data tells you to buy:
- Order 12 units of a star SKU and 4 units of a solid performer in the same transaction — no forced rounding up to meet a threshold
- Reorder a high-velocity SKU the moment it hits 30% remaining, rather than waiting until you can justify a minimum order across multiple products
- Test a new brand or flavour with a small initial order before committing to volume — validate STR before scaling up
- All orders ship with Ontario-specific excise stamps and full CRC compliance — no compliance gaps regardless of order size
Order exactly what your data tells you to. No minimums.
Arctic Distributions supplies Ontario SVS retailers with correctly stamped, CRC-compliant inventory across all major brands. Free shipping on orders above $1,000 CAD — no minimum order quantity.
