My wife went to CVS, bought something for $25, and was handed that traditional 3-foot receipt.

​Without breaking eye contact with the cashier, she glanced at the receipt and said, "I would like to return this," pointing to the product she just bought.

​I was confused.

​Refund processed. She immediately handed it back. "Now I’d like to buy it again with this 40% off coupon."

​She just hacked CVS for $10. Legend. 😅
