I bought from AllDayChemist, no prescription needed. It says a prescription, but when I talked to a man (Los Angeles phone number, no RX needed). You can order via phone or online. Electronic check from your bank account, takes about 5 days for fund transfer in Tennessee location if I remember correctly, order filled and sent to another country (to avoid confiscation). via DHL shipping. Tracking with DHL shipping sucks, but if you email AllDayChemist they can track it and give a 3 day arrival window. Once it arrives in NY, DHL gives an up date, then silence again. Arrives at your door 5-7 days later. Lengthy process, but I purchased 100-12mg tabs, along with azithromycin, and split with a friend. She, her husband and her father all got sick, took it and were better in 48 hours. I suspect there will be a run on OTC In Tennessee and might be hard to obtain. If anyone has purchased in Tenn. successfully, please let us know.
