I don't think it's Pari - I think it's Walgreens taking advantage of people. If it weren't for this site, I would have had no idea that you could just go online and buy one for $15, and I would have sucked it up paid the money (if I couldn't have gotten one from my clinic). I've heard that the pharmacy chains are almost always the most expensive place to buy prescriptions, so I'm not surprised they are that way with medical supplies as well. I just didn't know it could be almost 20 times more expensive!
