The surgeries available at Walmart are not of high quality, but they are very very cheap. You can get better quality procedures at Costco, but you have to buy way more than you want --- who needs a dozen heart bypasses? I can barely get through a quadruple myself. I usually just end up getting most of my surgical procedures at Target when I'm already there picking up toilet paper or something. Except for organ transplants --- I'm willing to pay a bit more and get those at Whole Foods, because I like to know my organs are organic.
