BD basically owns the Mercier brand and as the name implies they only sell it to you direct, no resellers.
the bike tho is genetically the same frame as a KHS Flite 100 that you may be able to get from dealers around town but usually costs way more. (not direct)
craiglist isnt a bad place to search

boy i didnt even know they had the black in matte but i guess they do and its popular enough to be low stock
the bikesdirect rep uses this forum, someone get him the user name i forget. try PMing him to see how long til its back in stock, or ever will be ;D good luck.
