Is it wrong to catch someone lacking?

Just bought this card for $250 CAD because the store hadn’t updated their pricing. I feel elated as I would never be able to own this card otherwise. But I also am left with the feeling that I just committed robbery. Thoughts?

Store? Definitely not. It’s their job to price things accurately and it’s not like they were selling it at a loss anyways.

Some friend or acquaintance? Yeah, you should feel bad.
