Social eCommerce startup makes you an entrepreneur upon sign up

Everr wanted to buy a product but couldn't find it? You asked around from family and friends and they still didn't know where to get it? You changed course and headed to a full blown market but still got back empty? Then finally, you visited a really popular eCommerce website with the certainty of getting it and still couldn't find it?! This situation gets awkward and annoying because you keep seeing a lot of people moving around with what you wanted to buy.
