$3 Benefiber Target coupon should still be available on their website and it combines nicely with $3 Benefiber Sticks manufacturer printable coupon. These are about $4.50 at Target so you get a bit of overage!
Another way to get a Target coupon for this is the new little coupon booklets at Target's Pharmacy. The $3 Benefiber is in there too. They were behind a little display at the one on Muldoon. I picked one up while they were closed for lunch and they look like they are there for anyone to pick up not just pharmacy customers. Go HERE for a list of all the Target coupons it has in it! Thanks to the Frugal Find for listing them!
