When is October Prime Day 2025?
This year, October Prime Day will run from Tuesday, Oct. 7 through Wednesday, Oct. 8. It will be a two-day sale, compared to four days for July
Does Costco also hold a sale for Prime Day?
Costco doesn’t hold a specific sale event to compete with the October Prime Big Deal Days sale. In July, it held a Member Savings Days event the same week as Prime Day. But you can expect to find the store’s usual monthly price markdowns during this time.
