June 4th, anyone know where to get cheap optifast??

Hi! I am set to have my surg on the 4th of June~WAAAAHOOOO~, however, I have to do a two week preop diet using the optifast program, the hospital sells this product, however, I am wondering if anyone knows where to get the product for a good deal. Right now I am looking at $300+ dollars for the two weeks, and financially I don't have that kind of money!
THanks~

first of all you dont need optifast , slimfast works the same and its under $1 a can but i found even better was get a blender get some triple whey protien powder some fat free yougert some strawberries or banananns or melon and make protien smoothies they taste great and no fat and plenty of protien before and after surgey dont waste your money you know whats good and whats not just do it!!!!!    good luck   by the way ive lost 144lbs with rny 6/10/08 and these drinks
