@Agro, shipping depends on how many springs you want to buy. If you buy less than 100 springs, it will cost less than 5$US, and probably quite a bit less than that, as it is only an estimate.
If you buy more than 100 springs, it should not cost more than 7$US for shipping worldwide.
BTW,just for fun, I just received a message from one of my other suppliers, detailing what I need to do to get the minimum order quantity to make 45% IACS Beryllium Copper custom springs.
It was really funny to see.
Basically, I would need to order 65 000 springs. Not 6500 springs. 65000 SPRINGS. Lol
So, I think I am going to stick with my main supplier for this group buy.
Unless some of you guys and gals want to order 1000 springs each
