Whole Foods is currently running a rare promotion in which after you spend $10 in-store, you will receive $10 to spend on Amazon Prime Day (7/16/18 at 3 p.m. ET). Promotional deals like these dry up fast so I highly recommend jumping on-board as soon as possible. Note, offer valid through July 17, 2018 or while promotion last. Limit one per customer.
Here is the exact fine print from Whole Foods themselves.
Spend $10 in-store, get $10 on Amazon
Prime members: Scan your Prime Code or use your mobile number at checkout in-store between 7/11-7/17/18 on a single purchase of $10 or more. You’ll get $10 on Amazon to spend on Prime Day. Prime Day deals start on 7/16/18 at 3 p.m. ET. Limit one per customer. Exclusions apply. Not available on Prime Now.
You're most welcome!
