I get my T from Costco, but have run into some major problems with them... I'm assuming that's just my location, though. I don't buy my syringes/needles there because they charge far too much and can't seem to understand why I need two different sized needles, regardless of what my prescription says.
Last year, I went to Wal-Mart to fill my T/needles/syringes, and while the T there costs $120 (I get mine at Costco for under $60), I was able to get a box of 200 3ml syringes with detachable 25g needles for $12. I haven't had to buy needles or syringes since, and despite my prescription having been for only 30 syringes/needles, the pharmacist at Wal-Mart made the adjustment for me so I could save some dough (the 30-count would have been $15, instead of 200 for $12).
