VistaVitamins vs. All Supplements

Does anyone on here use VistaVitamins? If so, do you find it cheaper to buy the VistaVitamins over buying seperately all other supplements needed post-op? Or is there another vitamin where I can get all needed vitamins/nutrients/minerals/etc. ? Basically.. do you think VistaVitamins are worth the $85 for 8 weeks? Or should I buy everything seperately?

I use optisource chewables for after bariatric surgery. It is through walgreens. (on line) and is $24.00 a month.
