The old joke about the difference between a used car salesman and a computer salesman comes to mind. ("...the used car salesman actually knows when he is lying to you!")
I'm not sure what legal basis there could be for anti-incompetence laws for web stores, nor how easily they might be passed. It'd likely have to be federal law, in the U.S. (At the state level, there are some nice, simple laws about in-store goods where the shelf says "Price $X", the check-out scanner say "Price $Y", and $Y > $X...)
My approach is mostly to have a long memory, and loose tongue, about such things. And to mostly shop at places considerably more competent and expensive than Target or Walmart.
