Upload & Sell: Off
They're all coming from China anyway. But I'd be happy to order them from China then sell them to you over here if they'll make you feel better.
Exactly what I was about to say and somewhat amused no one has said it sooner.
I have bought USB's from China in the Hundreds at a time and got different designs for my event work. I pick one for the boys, one for the girls and a generic one that is non descript. Biggest batch was 500 and they sent them to me free.
All these other companies are just buying from china and putting their substantial markup on them. I was buying 4G sticks for well under $2 and never had a problem with them.
I could buy 1G sticks, custom styling ( hamburger, fish, car, whatever, there is a million of them) for under $1.
The company I was buying off had a min order of 50 but I did get an initial sample order of 20 with no problem.
Buying off these other companies makes no sense to me when You can get them just as easy from china for so much less and have them inside a week anyway.... Often for free if you order enough.
Unlike US suppliers, Postage from China is not insulting in it's cost and airmail and rapid delivery on these things is very affordable. Not that you'd need it if you were ordering 50 drives so you had some in reserve.
