So, you never went back to Target and got a refund when something went on sale? Or at least inquired?
I personally see nothing wrong with asking. All of us (based on what people have posted) just stated we weren't happy that others had gotten better offers even though we were long-standing good customers. I didn't read where anyone even threatened to close their accounts.
Chase could have politely said "sorry" and done NOTHING. They didn't. They chose to keep their existing customers happy.
Sorry, but in a world of "bonus offers" for checking, savings, credit cards, HELOC's, Mortgages, etc.....I think we'll see more of this in the future.
