I just happen to have one of these coupons in my wallet so here's what it says:
Shop in store, by phone or online
$3 Free toward your next product purchase of $3 or more.
Now for the fine print:
Coupon valid for 3 months from date of issue. Valid in Staples, by phone at 1-800-333-3300 or online at www.staples.com
. Limit one per customer, nontransferable. Minimum purchase requirement of $3 must be met with purchases to which no other coupon or instant savings offer applies. May not be combined with any other coupon. Coupon must be surrendered. No copies/facsimiles. no cash/credit back. Not valid on services, gift cards, postage stamps, prior purchases from Awards.com(tm) or on other provider Web sites. Tax and shipping not included in calculating minimum purchase.
