Here's mine (not too accurate because OPSEC and unreliable memory).
Not for competition, I just want to share it.
I first heard about SR in 2011 and placed my first order in 2012. I paid like 10 BTC for 5 grams of weed. I was excited like a kid when I received my first pack. I ordered mostly small amounts of weed at first.
Since 2014 I ordered MDMA, LSD, marijuana edibles, powdered shrooms, 2C-B, DMT and pharmahuasca.
I've not been too lucky with MDMA: the first pills were bunk, on my second order the market exit scammed, and I'm still waiting for the "reship" of my last order.
I think I was scammed 4 times in total (2 markets, 2 vendors). I must have lost about $200.
I used SR, The Marketplace (awesome market; brilliant UI + multisig in 2013), Evo, Blackbank, Agora, Alphabay, Nucleus, East India Company and Hansa, in this order.
I have no idea how much I spent, it was always small amounts. There's no doubt I'd be wealthier had I kept my BTC for myself in the early days, but I regret nothing. I learned a lot from some of these drugs, they helped me become a better person, more loving of myself and others. The DNMs are a blessing.
What's your story?
This one time I ordered a shitload of coke and got fucking zooked for a week.
