Alrighty so about 2 weeks ago I placed an order for what would clearly be a resale amount of drugs and it has yet to arrive; it was a domestic order. I placed another order for the same quantity from the same vendor a few days later and that shipment has arrived and did so with no delay (I frequent the vendor I'm getting from and know his shipping times to my area). I've actually never had a delay, and have been active in the markets since the SR1 days. Anyways, should I now consider this address burned? Would it be possible for LE to stop one package but miss another? I can't imagine USPS simply lost the package; I work for a store that sends hundreds of (legitimate) items daily through USPS and we never lose anything. Also I don't believe LE would let one through to nab me in the process of distributing it while they held the one they've found because I've already flipped it, and they wouldn't have given me this much time to do so.
Oh, I guess I should add that the vendor did refund me and has done quite a bit of business with me in the past so there's roughly a 0% chance this was a scam attempt.
Interception, while entirely possible, kind of fades next to the chance of it just being a mail fuck-up - lost in the system, sitting in a neighbours, parked on the other side of the country etc.
Be smart and clean house, maybe use another drop for a bit - but don't be surprised to find it on your doorstep in the next couple of weeks.
