Brag: CVS Extra Care pays me moniez back

[pookvis]

Here is my story, feel free to jump to the cliffnotes. I had a 3dollar off coupon to CVS whenever I buy 15 dollars worth of things thanks to CVS's extra care etc etc. I went in to buy a cola and I was considering spending another 13 usd for only 10 usd when I decided to use it some other time. the ALL OF A SUDDEN it prints me another one becuase CVS is taking extra special care of me. Now I can buy 30usd worth of things for 24usd. What do I buy?

Beat: no beer at CVS
Variance: Answers in MS Paint?

Notes: I can buy 30usd worth of things for 24usd at CVS. What do I buy?
