I've only done one Pinkberry shop and accidentally ordered a medium (I pointed to the small cup, but when she held up the Medium and asked me to confirm, I said yes... guess my brain didn't want to trade down once I saw the yogurt-y goodness that would fill that cup up). The cost was $0.95 over the max reimbursement in my fairly high cost area. I'm surprised to hear that others can't get a small (or heck even a child's size) within the allowable reimbursement.
I had to order one topping per the guidelines, and ask for a taste (really had to twist my arm on those requirements) as I recall.
Mmmm, it's a hot day here today, some fro yo would really hit the spot! I need to check to see if there are any shops available near me.
