I often browse CL for free/cheap Lantus and Levemir insulin in locations where cats being helped by DCIN are. I browsed in some major cities, even though I don't have cats there. Thought these postings might help others. Macon GA, posted 10/26, Lantus vials at $25 each. Detroit, posted 10/26/10, 5x3ml Lantus Solostar pens, $25/box. Detroit, posted 10/19/10, 5x3ml Lantus Solostar pens, $20/box. Detroit, posted 9/27/10, leftover test strips, syringes, and lancets from a diabetic cat. Free. Minneapolis, posted 9/21/10, 5x3 ml Lantus pens, $100. Certainly not the cheapest I've seen, but cheaper than even the Canadian Mail order pharmacies. Butler (North Jersey), posted 10/12/10, 19 Levemir Flexpens for $200. This is a great deal if some folks wanted to go in together. In fact, DCIN wouldn't mind going in on this bunch. Phoenix, posted 10/29/10, Lantus 10ml vial $50. Scottsdale AZ, posted 10/4/10, 10ml vial Lantus $50. Escondido CA, posted 11/3/10, Levemir pens $12. I cannot say whether these supplies are still available, but it's worth an email or call. Please protect yourself and your money when dealing with a CL seller. Take away message--it doesn't hurt to check Craigslist in your area for insulin and supplies. You might even consider posting an insulin/supplies wanted ad. Amazing people want to help.
