For the outlet shops... I bought some things for DD... kept the tags on and receipts in the bag. One item was "lost" for some time in the house (or I thought I might have returned them) well found it and it was over a year from purchase. Brought it back to outlet with cc in hand. They didn't even bat an eye... credit put back on card. Give them a call just in case but I'm sure you won't have a problem. It's better to have the credit back than have something sitting in closet.
Good luck
