Should you keep your receipts?

Hmm.  Do you mean do you need them, or is it a good idea to keep them?

Do I really need them?

Well, if you’re able to get a refund, then you really should have the receipt.  If you get a refund, the store can’t say, “We can’t refund you, you don’t have the receipt.”

That is true.
If the store does give you a refund, you should keep the receipt, but you can just hand it to the store at a later date if you need to.  They’ll know it’s the receipt from your purchase.  If you’re not getting a refund, you can always throw the receipt away, so long as you’ve paid for the item.
I suppose it might also be good to have receipts, because then, you might be able to find out exactly what you paid for something, if that would help you later.
