I'm with mystery2me. Why spend $4 on 2 bottles of water when you can get a case of 24 for less (on sale). The exception is when it's been a long day and I've underestimated the amount of filtered water brought from the home tap. In which case, I'll get the any size 99 cent soft drink and fill the jumbo cup with fountain water.
When I can find them:
Mike & Ike small box, 3/99c
Tootsie Pops, 25 to 50c
Little Debbie Cake, $1
Pop Tart, $1.49 to $1.89
Cheese sticks, 99c to $1.29
Small chips, 2/$1
Oh Snap veggies, $1.59ish
Bananas, 33c to 99c
I have a snacker at home who lives on candy and junk so most is not for me. Our teeth can't handle peanuts any more.
When the reimbursement is generous, I might come home with a loaf of bread or quart of milk or some needed grocery item but I'll definitely get one of those packaged berry and cheese danishes. That one's my special treat for being a good girl.
And I can't stress strongly enough: CHECK THE EXPIRATION DATES!
