The Sunday Tribune (and probably other papers as well) has a full-page ad in the first section, saying that for three days only (24, 25, 26), when you scan your loyalty card at the Magic Coupon Machine, you will get a $5 off any $20 or more purchase.

NOTE:  The coupons are only supposed to print out one time per card and expire the next day.  In other words, if you scan your card today, that coupon will expire tomorrow.  Wait until the 26th and the coupon will expire the 27th.  Now, if you are looking to place a special order, depending on when your store gets delivery, this might work very well (obviously every store works differently).
