I got mine at Walgreens, $175 I think. No problemo. Just go in the middle of the day when they're not super busy. I called and asked the pharmacist when would be best. I wasn't current, I think it had been 12 or 13 years since the last one. Really, it took more time to make the copies of everything they want copies of for Indoc.
