I am sorry man, but from a simply business plan perspective this makes absolutely no sense. If you are willing to hold inventory at the end of the supply-chain in the form of a domestic warehouse, why do you not hold inventory at the upstream in the form of a international warehouse. This not only makes logical sense, but also would lead to better margins by you being able to get better prices from larger orders.
Also in a previous post you stated you were getting your raws from Beligas, but now you are drop-shipping from a manufacturer (this means he places your exact order with a manufacter and ships it to himself... then ships it to the customer after skimming his profit) ?
