I have done the one with the small fee. The gig is they are comparing the cost of the drugs with the RX discount plan vs. insurance co-pays etc. I had to go back twice to get my medicine. It is a good thing if the drug store is close. This was abour 6 months or so ago. The idea may have changed.
The report was super super easy if I recall.
It turned out for me the co-pay was a better deal, but I had to check the cost of the prescription discount plan. OP is this the shop you are referring?
