Print this Renu Fresh or Renu Sensitive Multi-Purpose Solution $2/1 coupon quickly, before it disappears.  My local Walmart has the travel size for only $1.47, so FREE after coupon.  Walmart does allow you cash back if the coupon value is more than the price of the item.  This coupon states in fine print that it’s not redeemable for more than the purchase price, so you may or may not receive the cash back.  Remember, you can print each coupon twice.
