Seedsman has been good to me. Not fast, but good selection, easy order.
Personally, don't see why anyone would order just a few seeds? As a business owner, all that pissing around for a couple bucks. Not worth it IMO. I am surprised seedbanks allow small orders.
Personally, perfer larger orders less frequently. Keep some inventory, a backlog of grow plans.
This way one does not need to worry if a order takes one day or 5 weeks.
As far as steath shipping goes, it's a no brainier. A good idea if you live in a proabition county. Me, I am a legal med grower in a legal state. But use stealth shipping, because of federal.
