They don't anymore. Many of these so called 'companies' today, and this is not a cheap shot at any one individual, but they are nothing more than resellers. They don't care about reputation, integrity etc, all they want is to make a fast buck. Shipping if you get it by the connex full, is not too terribly bad. At least it didn't used to be. you go through conglomerators or whatever they are called, get a bunch of these half connex / full connex loads, enough to put in a cargo hold and off they go. Butter the right palms and they pass customs with barely a glance.
China has a HUGE, or had a huge interest here in the US, they'd ship in shit by the boatload literally, and dump it off into warehouses to just store it, until it's sold to smaller distributors. Look how many chineese sellers there are on E bay, most of them drop ship out of the same shitty warehouse complex in New Jersey or wherever. You will see 100 sellers, all selling the same cheap thing, at a few pennies off from each other, if they even do that, all copying the same ingrish translations of the lies the product supposedly does. 100 different sellers, the same damned thing from the same cheap manufacturer. That's just E bay, now lets throw in Amazon, and how many whore out their cheap crap via bots on craigslist etc etc.
If you do happen to have something novel, not for long, they will steal your tech, and sell YOUR item, for 5 bucks cheaper via one of their E bay shills. Good luck suing someone you don't know overseas. E bay and the likes tend to turn a blind eye too to this stuff, they get their 10 percent so don't care about 'all the other stuff'. Pay pal is in bed with them too so. Even if an account gets canned, another one pops up almost overnight, self sells a few hundred items, and poof, a preferred BESTEST EVER seller on E bay.
I have a feeling though once all this crap is over, Made in America is going to become a thing again, and it's about damned time too!
