I bought my grand son a t shirt with a pro wrestler on it, which he dearly loves. We got it at W-M, along with some other things. When we got home I noticed that it hadn't been scanned.
I told him that we had to go back and pay for it. He asked me if it would be alright to wear it back to the store, I told him ok but leave the price tag on it. They scanned the tag while the shirt was on him. He was proud of that shirt, tag and all.
I bought a blouse one time that still had the plastic anti-theft device on it, the blouse was wrapped in a white plastic bag on a hanger, so I didn’t see it until I got ready to wear it. Good thing I had kept the receipt, as it was expensive. It didn’t set off any alarms when I left the store, but I sure surprised them when I went back in there, LOL!
