We ordered a batch of our kids medicine from CostCo a few days back. It turned out to be fairly easy. Shipping is free and they worked well with our HMO. We had to have our doctor phone in the presciption, but they did that without a problem. Now instead of having to remember to run to the pharmacy, I can just sit down at my computer and reorder the medicine. We even got syringes (which weren't listed, but I called them and they gave me the name to use to order them) I was very satisfied.
