The minimum order quantities are all over the board, anywhere from 1 to several thousand. there is obviously a price break per unit when you order in quantity. the shipping is not worth it in my experience for anything under 100. as your dealing with individual factories first hand, the prices can vary pretty wildly. i have seen nucs go from 2 dollars a piece to 7. its a pretty straight forward process to get a quote, and you do get to talk to people, go on and see what you can get, just remember to see what shipping will cost. for the quantaties i was ordering it ended up being cheaper to wait for a sale at mannlake.
