So I made a throwaway for my DNM stuff, but I was wondering: How many packages per week is too much? While I have not ordered from DNM too many times, (4 times in 4 months), I do a lot of legal online shopping as well. I'll usually get at least one package per week. Some weeks it's 2. Is this a suspicious number, or will the post office not think of it too much?
Your last statement is correct; your local mailman couldn't care less about what you get in the mail or how many packages you receive, as long as they're all addressed properly. He has his delivery job, and just wants to get it done and go home.
Buyers like yourself do not have their packages profiled. Vendors do. A buyer's biggest worry is when a vendor gets compromised, so always encrypt your address. As for your package frequency, think of the amount of Internet commerce going on every day -- millions of people get 2 or more packages a week. It's not exactly an anomaly.
