Coupon Savings for Walgreens – May 20 & 21 only This post may contain affiliate links. Please see my full disclosure policy for details. May 19, 2009 19 May Pin0Share0TweetGoogle+0shares Here is a GREAT coupon for Walgreens! It is good only for May 20th and 21st. You can get $5.00 off of a $25.00 purchase. The fine print says that the $25.00 must be AFTER any coupons and other savings, but still not a bad savings!!!
