Online arbitrage sellers live and die by turnaround speed. The gap between a profitable retail find and a stranded ASIN is often prep latency — not the deal itself.

PrepKingz receives OA shipments within 24 hours, applies FNSKU labels from your Seller Central account, polybags and bundles to spec, and builds inbound shipments on your routing plan.

Per-unit pricing from $0.80 at Elite volume. No monthly fee. Mix SKUs in a single inbound without renegotiating your rate card every month.

Common challenges sellers face

Prep backlog kills ROI

Inventory sitting un-prepped is capital sitting idle.

Label mistakes are expensive

One wrong FNSKU can hold an entire shipment.

Scaling DIY prep breaks

What works at 200 units/month fails at 800.
