yea, you need to set the price. I know that street price for 1 mandrax is around 4-5 bucks(so says the news). If you buy in bulk, Im sure you can get it substantially cheaper. Its all about supply and demand. If there is a big demand, you can always raise your prices until it levels out. Another thing that you will have issues with. Anyone less than 45 years old most likely has never tried it. But, im sure you will get a lot of "testers" and once they find out how good it is, they are yours.. First, Price it at the lowest you dare. figure in all your costs. product, shipping, btc fluctuations, etc. Then if you get slammed, you know you can up your prices, inch them upward til you find an equilibrium.. Im guessing with onzees and twozies, you could easily charge 10 bucks per. Then give discounts for packs of 10, 20 and so on.. Im betting 99 percent of all your first orders will be "test" purchases. But, this I do know, If the price is right. It will be successful..
