Online Arbitrage Prep Center Guide: What to Send, What to Expect
Key takeaways
- Arbitrage shipments are mixed-SKU and unprepped, unlike single-SKU private label shipments from one supplier.
- Every unit needs the original retail barcode fully covered and a new FNSKU applied from scratch.
- Send a SKU-to-ASIN packing list ahead of or with your shipment to speed up receiving and reduce miscounts.
- Arbitrage volume rarely reaches the discounted high-volume labeling tiers, so budget for standard per-unit rates.
- Free receiving and inspection matters more for arbitrage shipments given higher condition variability.
Private label sellers ship hundreds or thousands of identical units from one supplier. Online and retail arbitrage sellers ship a mixed pallet of one, two, or a handful of units per SKU, sourced from dozens of different retailers, with zero chance the supplier applied any Amazon-compliant labeling. That difference changes what you should expect from a prep center and how you should package your shipments before they arrive.
What arbitrage sellers typically send
- Retail-packaged items purchased individually or in small quantities across many different SKUs
- Items with existing retail barcodes that are not FNSKU-compliant and need to be covered or replaced
- Mixed condition, occasionally including open-box or clearance stock needing inspection before it is prepped
- No supplier-side prep of any kind — every unit needs full prep from scratch
What good arbitrage prep looks like
- Per-unit FNSKU labeling with the original retail barcode fully covered, not just partially obscured
- Individual inspection given the higher variability in condition compared to a single-supplier private label run
- Poly bagging on items Amazon requires it for, sized correctly rather than generically applied
- Accurate unit counts against your packing list, since arbitrage shipments are more likely to include a picking or counting discrepancy than a single-SKU pallet
How to package your shipment before it arrives at a prep center
Send a packing list or spreadsheet mapping each SKU to its ASIN and unit count before or with your shipment. Group like items together in your own boxes rather than one undifferentiated mixed carton — it speeds up receiving and reduces the chance of a miscount. If you already have FNSKU files generated in Seller Central, send them ahead of time rather than at drop-off.
Pricing expectations for arbitrage volume
Arbitrage shipments rarely hit the volume tiers that unlock the lowest per-unit labeling rates, since the practical unit is one SKU at a time rather than 500+ identical units. Expect to sit in the standard per-unit tier on our published rate card rather than the high-volume discount tier, and to benefit most from free receiving and inspection given the higher per-unit handling variability.
Frequently asked questions
Can a prep center handle mixed-SKU arbitrage shipments?
Yes. The main difference from a private-label shipment is per-unit handling: each SKU needs its own FNSKU label over the original retail barcode, and inspection happens at the individual unit level rather than by sampling a single-SKU pallet.
Do arbitrage sellers get the same per-unit pricing as bulk private label shippers?
Usually not the lowest tier, since volume discounts are based on per-SKU quantity and arbitrage shipments are typically one to a few units per SKU. Standard per-unit rates apply; free receiving and inspection are included regardless of volume tier.
