I'm wondering how do so many domestic vendors get their packs profiled? If they see using a USPS flat rat box with a printed label shouldn't they be fine? The only few ways I can think of are..
1.) Using the same return address for all packages.
2.) Paying in BTC from the same wallet everytime.
3.) Using the same internet connection when paying for all shipping labels.
I mean the most average vendor should be able to figure out these are big no-no's. So how do domestic vendors seem to manage getting their packs profiled?
