Can I get a copy of a receipt from a past purchase? I need proof of purchase.

Yes create an account and it'll have all your purchases you've ever made

Yes, within 2 years of purchase date as long as you uses a phone number and or a credit card at time of checkout. We can look up any purchase and reprint the receipt. If you only used cash and didn't use your phone number, you're SOL.

Yes, you have to either have the Rewards account (phone number) or the card you used at the time purchase
