Amazon has officially announced the important preparation deadlines for Prime Day 2026, and sellers should begin planning inventory, promotions, and deal submissions immediately to maximize visibility and sales during one of the biggest shopping events of the year.
Prime Day consistently drives massive traffic and conversion spikes across Amazon marketplaces, making early preparation critical for brands that want to secure strong rankings, better inventory placement, and higher sales velocity.
Prime Day 2026 Deal Scheduling Deadlines
Amazon has confirmed the following promotional scheduling deadlines for sellers participating in Prime Day 2026:
April 30, 2026
This is the final day to schedule:
- Best Deals

Sellers who submit these deals before the deadline will also receive a $50 discount on the upfront fee per deal.
This early scheduling opportunity can help brands lock in premium promotional placements while reducing campaign costs.
May 26, 2026
This is the final deadline for:
- Prime-Exclusive Best Deals
- Prime-Exclusive Lightning Deals
After this date, sellers will no longer be able to create these promotional deal types for Prime Day.
Ongoing Promotional Opportunities
Amazon will continue accepting:

- Coupons throughout the entire Prime Day event
This gives sellers additional flexibility to adjust pricing strategies closer to the event based on inventory levels and market competition.
Important Prime Day 2026 Inventory Deadlines
Inventory readiness will play a major role in Prime Day success. Products that arrive late may lose the Prime badge eligibility during the event, significantly impacting visibility and conversion rates.
Amazon has announced the following inbound shipment deadlines:

Deadline for:
- Amazon Warehousing and Distribution (AWD) shipments
- FBA shipments using the “minimal shipment splits” option
June 5, 2026
