Here is something I posted last year, when we went searching for cheaper alternatives:
The MRC-6, we found a substitute at a few weight loss clinics, KLB-5. KLB-5 is the exact same as MRC-6, minus the B-6, which you can get very cheap anywhere (not to mention, there is pleny of B-vitamin in every multivitamin sold in the centers, or elsewhere!). The bottles were $24.00 for 180, which here is saving $15 a bottle. (last time I checked)
