Can i trade in my iphone 4s lifeproof case for a different color?

I have a red lifeproof case and I want to trade it in for the teal or purple one… Is this possible? I got it at best buy and I don't have my receipt, but I have the box I purchased it in.

If it has the barcode you probably still can, my mom does this all the time at walmart. She loses the receipt, decides she doesn't want the item anymore and they exchange it for her if it still has the barcode on the box

If you first open it there's no returning it unless you try to put it back in like it wasn't even opened
