My mother in-law always shops at Old Navy for my husband and I. Every year I tell her my size, every year she buys me a larger one and without the gift receipt.
I went in to exchange it for smaller one, NOPE! I have to give them my item and they will send me a check.
I then have to wait for the check and then go back and hopefully they still have what I wanted. By the time I get the check they don't have the color or the size, I just want a smaller size,
