lex said:went to pep boys and the coupon wouldnt scan and mgr said it was 10% off 30! they suck.

Maybe that manager can also explain what "Limit one coupon per customer. Limit of two per coupon. " means.

My Pep boys accepted 2 coupons. I could have used as many as I wanted, they did not care.
As a matter of fact I saw the screen as the manager entered it, and there was a button they pressed that came up and said "$10 off $30".
So it looks like it is in their system in some way, and maybe some are getting the wool pulled over their eyes.
