Diabetic supplies , test strips /meters) while traveling

My test strips are covered under Medicare part B, durable medical supplies. Since I am on a insulin pump I use 6 strips per day. I get mine from Walgreens. If you have a Medicare supplement the cost is almost 0. To get more then 3 per day your doctor will have to fill out a form for the reason to use more then 3 per day.
