I got a prescription for it and use a Canadian or online pharmacy I pay $18 for 100 tablets. There is no need to pay huge prices for this stuff. It comes prepackaged in blister packs and stays fresh a long time. You must have the prescription to get it tho.
My MD wrote for 90 tabs at a time, and they come 100 to a pack so remember that when asking for the script.
Let us know how it goes.
