I'm supposed to bring a magnifying glass and compare the stock numbers. This was the same brand, same name for the product, same packaging, same size, everything. And they put in on the shelf and put the sale tag on it. I shouldn't have to go THAT far. I didn't just pick something up off the shelf thinking it was the same item. It was on the sale shelf where they put it!
You shouldn't HAVE to compare stock numbers and/or stand there looking over the shoulder of the cashier to make sure they're not stealing from you. There should be some level of trust you can depend on, but that's too much to expect in this day.
