Three consumer groups have filed an amicus brief on behalf of the FTC, which has moved to block Whole Foods’ attempt to purchase rival Wild Oats. A federal judge is expected to rule on the case soon; in the meantime, Whole Foods earlier today extended its offer to Wild Oats until August 15th. Omg this is totally like when Heidi decided to move in with Spencer on The Hills! (We had to go to Wikipedia to write that sentence.)
