I used most of my snack credits at the gift shop.
We got the essentials:
1/2 gallon milk
2 liter diet coke
jelly beans
mickey cookies
baked lays
It basically was anything $4 or less. The cashier would ring it up and if the card let it go through then it was mine
I didn't use any snack credits at Pepper Market except for the dessert with the CS. There wasn't anything that great. (Muffins, rice Krispie treats...)
