Coupons.com has a new Rite Aid printable coupon available for some locations. Just go here, look under the Coupons caption on the left hand side and click on the Rite Aid link.
I got a $5/$25 purchase but others are reporting $4/$20 and even $3/$15! Why the variation? Coupons.com shows different coupons based on your zip code. Note: this coupon expires 11/3/09.
