Why Bi-Coastal Warehousing Saves Amazon Sellers Money
10 November 2026 
Amazon charges an Inbound Placement Service fee when sellers ship all inventory to a single fulfillment center. The fee ranges from $0.27 to $1.58 per unit depending on item size.
With warehouses on both coasts, ARDI splits your shipments at origin — sending West Coast inventory from California and East Coast inventory from New Jersey. This eliminates or reduces placement fees while cutting transit time to Amazon FCs by 1–3 days.
| Factor | Single-Coast 3PL | ARDI (Bi-Coastal) |
|---|---|---|
| Inbound Placement Fee | $0.27–$1.58/unit | Reduced or eliminated |
| Transit to Amazon FCs | 5–7 days cross-country | 1–2 days from nearest warehouse |
| Carrier Coordination | Two separate companies | One company, one invoice |
| Port Coverage | One coast only | Long Beach + Newark |
| Coast Restriction Risk | Stockout risk | Redirect immediately |
