We see that some clients want to buy only small quantity stepper motors like 4, 5 or 6 pcs from RobotDigg. It is OK for us, BUT the shipping cost will be more than the stepper motors themselves. Why not buy them locally? We can Not post stepper motors, and for items over 1Kg, the postage is nearly the same Cost ship by couriers(FedEx, DHL, UPS or TNT) to U.S., Canada and European Countries.
To average shipping cost.
