Placed a 100 dollar order last week and the vendor acknowledged it, but canceled it and refunded me my bitcoins 2 days later without any other communication. I assumed that he didn't ship out for whatever reason, but the very next day lo and behold, my order showed up at my doorstep. No idea what the fuck happened, but I kinda feel bad. I'm not sure why the heck he'd give a refund and I haven't gotten any communication since. Should I let them know and offer to pay? My conscience is killing me. But then again free drugs... hmmm...
If it was PFM/Humboltfarms/NiceDrugs or any of his other accounts, you are better off keeping your mouth shut and just enjoy your free drugs or sand. Sometimes being too nice to the wrong person can bite you in the ass.
