I searched on ebay for some USB wall plugs and micro USB cables, and I came across this vendor who carries these in rainbow colors - here is the link for a bright red U.S. wall plug:

I know some people like to go with the bright red raspberry theme, so these caught my eye.
That page offers quantity discounts - selecting quantity 10 got me a price of US$9.49 for all 10. They also have micro USB cables in the same colors, though just one meter long, for $6.40 for 10. They offer free postal shipping worldwide. So that is what I just ordered to complement my newly arrived, long awaited order of ten RPi model B.
