About 20 years ago, I bought four stackable indoor chairs for our basement in the Denver area. They were all in one box. I think they were around $30/each. I signed the CC receipt without looking at the amount. When I got home, I noticed the receipt was for around $30. I guess they scanned the bar code on the box, which was only for one chair. I didn't drive the 10 miles back to the store and pay them the rest. Is that "stealing"?
