It is possible for Walmart to look up receipts if a debit or credit card was used to make the purchase. The date and time of the purchase are required in order to find the receipt in their computer system. You must present your card to a Manager at Walmart for them to perform the receipt look up.
If the date and time of purchase is not available, you may also call the Walmart Electronic Payments Hotline at 479-277-2643 and have a copy of the receipt faxed to you. Knowing the exact total purchase amount will help them find your transaction more quickly.
Currently, Walmart will honor up to three returns without a receipt in a 45-day period. A cash refund is issued if the purchase was under $25. If the purchase was over $25, a Walmart gift card will be issued.
