If you do, how does it work? Is it worth getting?

I want to buy a couple of things but don't want to pay for it all right then and there. I will be able to pay it off though.

 

I've got one, since i needed an emergency part for my daily driver and did not have the cash at the time. It is just like a credit card, but only for use at Summitt. The apr on balances is 29.99%. So don't use it unless you can pay it off quickly; which is what i did.
