I am from a company called Alliance Electronics based in the UK, which special in refurbishing commercial vehicle electronic parts. We recently have seen a increase in need for the VDO Stepper motor, Part numberAW-MOT-012. I would require 5 units as the minimum purchase to check that they are correct and then I will place an order for 50 or 100 of these units, depending on price. Could you please advise on cost of these units in the quantities of the minimum order, 50's and 100's? Please include any postage costs.I also use a large quantity of the switec motors, XC27.589, up to 2000 units per year and would be interested in a quote on these in the quantities of 500's and 1000's please.
