The hard part is talking to the cashier and waiting for a manager, potentially having to argue with both, and looking like a cheapskate.

If you've ever shopped at dollar stores they are often understaffed with a long line, no self-checkout, and a single cashier on duty if at all. If you argue about pricing you will hold everyone up in line, maybe get dirty looks and possibly wait an hour for someone with the authority to come and clear it up. Another person in this thread also mentioned that they got screamed at and chased out of the store for "causing a problem": https://news.ycombinator.com/item?id=46182451

I have been to the Dollar Store (and similar) many times and have never witnessed anyone getting yelled at for saying, "Hey, I think this was a mistake. Can you correct it, please?" (or any other place I shop - especially the grocery stores). We tend to have very positive experiences when pointing out pricing errors. My mother-in-law made it a point to review the receipts ever time we went to the grocery store. No big deal. As other have said, sometimes you get +10% of your money back and other times you get it for free.

Yes, mistakes happen; yes, people get over charged. But to imply people are shamed for asking to correct the error just seems...odd.

I mean, that person actually got yelled at and had to leave the store. Some are more sensitive than others and just the fear of an unpleasant interaction is enough for some people. I've let small discrepancies slide just because the staff looked overworked and I didn't want to make them stop what they're doing, run down to the aisle and check prices and get their supervisor. For most I think it's just a time thing. It isn't worth a couple dollars to commit to an unpredictable amount of time going back and forth and waiting for a manager. I salute those lions like your MIL who stand their ground and fight back but there are also many, maybe most, who are just in a hurry or want to avoid confrontation.

		Thanks, I appreciate your perspective. One note about asking for a refund/price adjustment. Occasionally the store workers forget to pull the sale prices off the shelf when the sale is over. In these situations, the manager/workers are appreciative since they can pull the sticker that was left on by accident. Just my experience...
