There are some really oddball frauds going on with self-checkout. There was one guy who was eventually caught, who would make UPC labels for Lego sets. They would typically be for less expensive ones, but then he'd find really expensive sets and then place the less expensive ones. Then he'd sell the sets on Craigslist or eBay for less than retail price but more than what he paid.
It worked even if someone asked to see the receipt because often it would just note "Lego" or something similar, and security might not even have a close look at the box. And I've seen real items where there was an actual replacement UPC sticker over the original for one reason or another. Sometimes it was something imported and where there was a different item.
There are some things that can't be purchased at self-checkout because of age restrictions.
I have seen have some interesting cases, like stuff I've seen in the clearance section of a store and where there's a label indicating half or 75% off. But it had to be done manually. An employee would have to sign in and change that.
I have had some interesting things going on with loyalty programs and self checkout. It's supposed to be automatic but sometimes the programming is off and I don't get it immediately. I recently had something like that where I did choose a "digital coupon" but it just wouldn't work. The employee just said you can have it for $5, although the price with the coupon was a little bit more. But the receipt said something like "customer loyalty" or something like that. Once I had this special for canned soda where it was 4 12-packs for $10 if a digital coupon was loaded, but $12 otherwise. I noticed that afterwards and went to customer service. It was mix and match with different brands (Coke, 7-Up, Pepsi) but at customer service the clerk said they were having problems with the programming when brands were mixed and I was given $2. Didn't quite cover the difference in sales tax, but I wasn't going to push that.
