The thing is.... you have to pay extra to make them keep a record of the package being delivered, and the service is a tad slow. I could see national insurance now: "Well Mr. _______, I've got no record of you having diabetes here. You aren't getting that new pump"
But really, if it means that I don't have to show an insurance card every time I have to go to the doctor, I'm totally game, because that is a pain (mostly because my mom always has it and I usually go alone)
