This is an awesome solution to a pretty painful problem for me. The way I buy something is I typically spend 90% of my time researching and deciding what to buy and just 10% on actually finding the best place to buy it and pulling the trigger. Most millennials I know do the same and spend a lot of time on researching products, which is definitely time consuming. Pretty cool to see a viable solution here. Giving it a try now!
