In the weekly ad, there is a coupon to get $0.99 Right Guard or Dry Idea Deodorant. Right now, on coupons.com (see my bar at the top of this page), there is a coupon for $2.00 off! This will MAKE you $1.00.
However, if you take these coupons in, do not be surprised if Walgreens adjusts the $2.00/1 coupon DOWN to $0.99 since you can’t actually get money back. You can sure try to throw a filler into your cart that is at least $1.01 and perhaps you will get the full $2.00 off. This is definitely one where YMMV (your mileage may vary) as to what you are able to save/get for free.
You can also just get free deodorant with the $1.00/1 coupon that was in the 4-19-09 SS insert. There was also one in the 5-17-09 SS insert for $1.00/2. This one is not free, but will still get you $0.49 deodorant!
