Do all transactions need a receipt or whatever the salesperson gives you? What if the salesperson didn't give you any? How can I make my assignment valid without it? Yesterday I completed two assignments and reported back the results. Not knowing the receipt thing. Today received an email from them saying I should upload my receipts. Luckily I got one from the other store I shopped in but unfortunately I didn't have anything for the other one. Any help please? I don't want my assignment to be discounted.
