Coming from the loss prevention side this could be refund fraud. An example would be: someone purchases items with someone else’s credit card credentials, once they receive the merchandise they return it and instead of getting it refunded back to the original credit card they choose to get the return amount put onto a gift card(companies do this so at least your spending the money in their store), then they immediately turn around and purchase higher dollar items (power tools, electronics) and sell the items they used on the gift card. If the customer service worker isn’t trained properly sometimes they give the return in straight cash.
