I just got back from Staples while shopping out of town and those clerks were not happy campers. My friend and I printed out the $5 coupon and it showed up on their computer as already used. The clerk said she wouldn't take it. I said I hadn't used it before and they could check my Staples reward account. She called a mgr over and he approved it. Then my friend tried to use her coupon and the clerk got even madder and called a different mgr over who promptly gave us a lecture that he would honor it this time but never again.... So, good luck everyone but be warned that it needs a manager to override it.
