No. It’s if you were selling something in your house for $10. Somebody came in, crossed out the number on the tag, wrote down $1 and handed you a bill.

Then you took their money and gave them the item without saying anything.

Would seem like a weird situation but I don’t see how its theft.

I bet that would be most likely classified as shoplifting and/or fraud depending on jurisdiction.

Or a form of negotiation if done in plain sight.
