When I was shopping at Target the other day, I picked up a black cami/tank top for the Princess. She needed a new one, and it was marked down 30% so I added it to my cart. I had picked up quite a few other things and my total at checkout was just about what I thought it be, but nevertheless, I quickly scanned the receipt out of habit before I left the store.
While scanning, I noticed that the tank top had rung up as $9 instead of the $6.30 that was on the tag. I dug through my bags to be sure I hadn't gotten one that had NOT been marked down by mistake. Nope, there was the bright orange clearance sticker. So I took the tank and my very full cart over to Customer Service to get the price adjusted.
Yeah, it was only $2.70, and yeah, every single thing in my cart was either clearanced or sale with coupons or both, but in my world, $2.70 is $2.70 and it was worth the hassle of standing in line and getting my $2.70 back. The lady in Customer Service was as friendly and nice as she could be and handled my issue as quickly as possible and I was on my way.
Don't ever be worried about causing "a problem" when something doesn't ring up right. Yes, it can be a pain sometimes, but mistakes happen and as long as you are nice, 99% of the time, Customer Service will be, too. It is YOUR money and you worked hard for it.
