lets say a bunch of tvs, or laptops were bought. she could sell them for money, or if she owed someone money they may take the items instead of cash. especially if items can be sold for more than she owes.
I can't say I follow you on that one..if she returned items that were charged the store 99% of the time WOULD NOT give her cash back. The returned items are credited back to the credit card in which they were purchased. No doubt she spent money..probably cash advances taken out on the card or she outright charged what she needed.
