Rip Off or Not?

I found this orange in the middle of a bag of oranges that Albertsons offered at a discount. It was the only one in the bag like it, and the bag offered a dollar off. I figure the orange, which I simply threw away, cost a little over a dollar by itself. I figured driving down to the store could cost almost that much in gas anyway, so I didn’t try to get my money back.

My question is, should I chalk it up to the risk of taking their discount? When I bought the bag, it had never occurred to me that anything in it would be completely inedible. Also, do you think I’ll get in trouble if I re-pack their bag next time I’m there?
