International Marketing

In addition to an avid interest in renewable energy, I also operate a hobby shop and am inundated by emails soliciting business with Chinese companies. Hobby shop owners in the USA refer to most of these as the "Gray Market" and see it taking over sales from domestic companies to a great degree.  I am curious to hear other people's opinion on this subject about buying from foreign companies simply because the price is lower.  I buy from domestic distributors whenever possible, but see the market turning away from US to THEM as a current trend. Is there a possibility that THEM will own US in the future?  I am shutting down my business next year, as my local distributors are going belly-up in our economic decline, and wonder where the future will lead us?  Any opinions on this?  Jon C.
