I'm usually happy with any method that will fit through the letterbox if I'm likely to be out as my regular postie is a mate and he'll sign for anything that needs it, even SNDD, and whatever method if it won't fit through the letterbox and I am in.
Last Saturday I had a pretty hefty custom sorted out by TSM delivered. Heard the doorbell. Stirred. Didn't hear the letterbox. Thought, as I was drifting back off to sleep, 'fuck, it could be massive!', jumped out of bed in my PJ bottoms, saw postie and thrust open the door. Not the usual postie. He got me to sign his digital pad thingy. I made a squiggle. "You're one of my best customers this week!", says postie, handing over the massive parcel. 'Fuck', I thought, 'I've only had 3 parcels this week...' I give him a disarming smile, tell him that usual postie (who I obviously name) has been telling me for decades to stop buying so much shit off the internet. He laughs and tells me it keeps him in a job and goes on his way. I go back to bed and leave it to open until I get up for plausible deniability purposes, just in case he's a plant... Not really. I do go back to bed though and open it later. It was only 11:40am on a Saturday.
Makes me realise that on the days I have 5 packages all delivered at once and my usual postie says absolutely nothing that he's really a gem. From a stealth perspective I wouldn't have an issue with it going back to a depot then coming back to me, but I can see how that's a logistical ballache for a huge number of people.
Just one thing though, my username has been written on bags a few times now. I've mentioned it privately previously, and then it stopped, and now it happened again. If this was opened (for whatever incredibly tiny chance) I have absolutely no plausible deniability, especially on very large orders.
Other than that little niggle, I'd endorse TSM incredibly highly as they get me very stoned regularly with superb buds at keen prices, and their shrooms are pretty damn good too.
