There is a new Advil or Thermacare coupon  for $3 off 2 packs.  The coupon I printed does not have any restrictions on size so you should be able to find the little travel packs for FREE with coupon or for very cheap at Walmart or Target. The only catch is that you need to either like the coupon on Facebook or email it out to 3 friends to get that $3 value.  Otherwise the coupon is $1.00 in value. Use zip 85254 if needed to pull the coupon link up. I posted mine on Facebook and was able to print my coupon with no problem. You can find more coupons you might need in the coupon database.
