Even with safe MDMA, the risk of possession carries a far greater weight in a lot of the country than something like weed. So people tend to take more risks, and thus the price is higher. If you could somehow subvert this cost by buying in bulk through a trusted vendor on the Internet, you stand to make some money for your troubles. This is, in my opinion, the most likely reason why SR has large quantities of MDMA and LSD.
