question about protien shakes

Doctors have told me unjury and bariatric fusion are the best....also pricey lol...does anyone know a good site to get these is bulk at a better price. 

or does anyone know other shakes that are comparable, that are good, and are a little less expensive?   just curious.  i want to make sure i am getting the best product even if it costs more, just wondered what else people use.

and for vitamins same question?  will i be taking the same vitamin many times a day.  or many different vitamins throughout the day?

i have found i do not like the pre-made protein shakes, so i buy the powder and make my own. i have to take so many vitamins now that i take all the multivitamins in the morning and then spread the others out throughout the day
