Shoppers spent Day 1 researching and comparing prices across Amazon, Walmart, Target and Best Buy (57% of Prime Day shoppers compared Amazon’s prices to other retailers before buying). By Day 4, the urgency of a closing event pushed conversions hard, and sales jumped over 400% on the final day compared to the middle of the event.

May 27, 2026: FBA inventory must arrive at Amazon fulfillment centers (minimal shipment splits). This is the hard cutoff for standard FBA. Amazon may accept inventory after this date, but there’s no guarantee it will be processed in time. If it’s not checked in, your listings won’t have Prime-eligible stock when the event opens.

June 5, 2026: Last day for FBA shipments with Amazon-optimized splits. If you’re using AWD as a buffer, this is your secondary cutoff. The shift to June is literally squeezing every seller.
