Ever buy something at retail price…then find out a week later it went on sale and you could have got it even cheaper? Ouch! Avoid buyer’s remorse by saving your receipts! Most retailers will give you the difference back between what you paid and what the current price is within 14 days of the original purchase! They prefer that over you returning the items at full price and repurchasing it at the sale price. So, hang on to ALL receipts for at least two weeks after you purchase something in case it goes on sale.
