Street price in the states for a single pressed European MDMA pill is $20 at the minimum. Meanwhile, you can get these pills straight from the source for a little over $4 each on Agora. You're looking at almost 500% profit margins per pill. All you need are the connects and social circles to advertise them to, which isn't terribly difficult especially if you're in university, where there's a high concentration of ravers looking to get these things. I average about 2k a month doing absolutely nothing but selling these things, which is a TON of money for doing little more than answering house calls from customers.
