Would you open a department/specialty store credit card just to save money on a purchase? How much would it have to save you – $10, $50, $100, $500+?

I am annoyed by the sales clerks at Target / Macy’s / wherever that continually ask me to open a credit card, and try to entice me by saying, “It will save you $20 off your purchase today!”

Guess what? $20 isn’t enough for me. It’s gotta be at least $100. And even then… I’m not so sure.

My sister worked at Sears for awhile and was required to open a certain amount of new credit cards a month. Any insight into this?
