When I shopped with my wife for the first time, I was a little surprised that before leaving any store, she pulls her cart to the side and carefully goes over the receipt. The reason? Mistakes are made in pricing all of the time. I can’t count how many times things ran up for us at the wrong price. She would always go to the customer service desk and get an adjustment. I probably missed out on hundreds of dollars just blindly trusting the receipt my whole life. It’s nothing nefarious. Systems have bugs. Takeaway for me is that I can’t use a technology that doesn’t let me verify the price.
