Do People Actually Pay This?

[Bushead]

I work at Macy's and we are "encouraged" to really sign people up for credit cards. When you first get it, you get 20% off your entire purchase, which is really a good deal, but the interest rate is 24.5% I believe. If you miss one payment, you might end up losing all the savings you just got.

What's sad is that all you have to do is be over 18 to get one; there are many times I see high schoolers walking out with a new card (probably with a 75 or 100 dollar limit, but still) and thinking they saved some good money or their coupe of t-shirts purchase.

I have always wondered if it was easy to sign up for the credit card, pay everything off the next month, then cancel it. Does anyone have experience with working store credit cards that way?
