RobotDigg hope every 3d maker can buy their quality 3d printer supplies in a best price. From our order record, most of 3ders are good at Combine but some are not.
The ones who are not good at Combine may be not that familiar with our shipping policy and the shipping rate from China.
We have a promotion since August 2013, free shipping for orders over 200USD under the category Timing Pulley&Belt and Stepextruder Parts, to U.S. Canada and more and most Europe countries by FedEx, DHL, UPS or Aramex.
And another promotion would be free shipping for orders over 100USD by China Post Air Mail under 500g(A nema17 40mm stepper 300g and you can buy together stepextruder parts or timing pulley).
For the order weight over 1Kg we ship only by FedEx, DHL, UPS, TNT, etc to most of the countries except to Russia, Argentina and some east Europe countries.
To Combine to Be Wise.
