PatchMD
My friend who had the surgery in the US uses them and her bloodwork is excellent a year out, she just adds sublingual B12 2x a week. So I've decided to try them once I have surgery, just placed an order. They arrived within a week. They charge a flat rate ($12) for shipping and I ordered a 6 month supply. I didn't get hit with any duty, but you could, it's a risk. I travel a lot and they seem more convenient than carting around tons of pills.
