Anonymous 1: For me, [getting Bitcoins] used to involve a maze of prepaid cards sold at office supply stores. Now there are private sellers you can meet in person advertising online, but I now prefer the physical "Bitcoin ATM" [there is a permanent one at Fells Point's Bad Decisions, though mobile ones have appeared around the city, including one at Hampdenfest]. Once you have Bitcoins in your possession, there are several sites that operate as drug marketplaces where you can deposit them. Most people are familiar with Silk Road. Agora Marketplace is my current go-to site. When purchasing, you encrypt your shipping information in a way that only the person selling it to you [can] decode. Marijuana is definitely the hardest thing to ship in the mail, as it reeks, but somehow through the power of vacuum sealing and the apathy of the Postal Service, you receive it.
