Buying an Avery Binder? Get a Coupon!

I can't confirm this, but I read that Avery Binders are going to be Buy 3 Get 1 FREE at Staples beginning Sunday (8/7).  Here's a PDF coupon for a $1 off ANY Avery Heavy Duty View Binder!  I read the find print on the coupon and it doesn't say "limit one per customer" so I'm going to take a guess and say you could print three copies and get a $1 off each full priced binder!  But, I can't guarantee Staples will accept all of them in one transaction! Good luck!
