I don't think anyone has mentioned this yet in this thread, but there are a few compounding pharmacies from which you can mail order T, at least in the US. I haven't done it myself but supposedly it can be cheaper that route. (You would obvs need a prescription. I'm not aware of any establishment that will just sell you T without one, and I wouldn't recommend it if I did, because you just don't know what you're getting.)
Another reason to consider that method would be if you had issue with the type of oil used in the stuff available at your local pharmacy. Some people are allergic to sesame oil. I was allergic (mildly) to cottonseed oil but I started taking Zyrtec (certirizine HCl, an over the counter allergy pill) and I'm fine now.
But supposing you have any sort of allergy or intolerance, or if you'd prefer to save a little money, you might check that out. I get my stuff from Walmart for $13.88 twice a month (so about $30 incl. needles) and so I pay about $15 for each mL. That means I'm paying $150 for every 10 mL, and I've heard that you can get a 10 mL from Strohecker's pharmacy for about $60-70 plus a little for shipping. So you might want to google that or other legit mail order pharmacies, see what's what. If you do have insurance, your provider may be able to help you find the best option for the money.
Again, I don't know if that's a concern for you, but I imagine someone could use the info, so I just wanted to share that.
