In addition the Zantac money-making deal at CVS, you can also grab a slightly better deal at Target:

Zantac 75 – $7.59
Use the 20% off Zantac Cartwheel (deducts $1.52)
Use the $5 Zantac Product or Duo Fusion printable coupon
Submit the $4 Zantac Checkout51 offer
And sumbit the $3 Zantac Ibotta offer
= $5.93 moneymaker!

(While the $5 coupon does have the CVS logo on it, it is a manufacturers coupon and should be accepted anywhere.)
