Um, you want us to wait for a result? Finding the lowest price isn't hard it's called going to Amazon.com. What exactly made you think crowd sourcing lent itself to this type of problem?

I just don't see a need, I don't want to wait, I already know how to find the cheapest price.

...google searches for products also show prices...on demand.

Amazon always has the cheapest price?

Thanks! Interestingly, the experts can find a lower price than Amazon. E.g. a user was looking to buy a gaming console and one of the large merchants was having a anniversary promotion and had a great price. It is rare that a single merchant has the lowest price on all products all the time. Also, the experts can search for the lowest price across different product categories that are carried across different types of merchants i.e. it works for items ranging from electronics to Broadway tickets to auto parts.

Often, I am willing to pay a few bucks more to purchase from a retailer I like...or who I am comfortable doing business with.

I think you may be assuming that people only check one place for a price...consumers tend to look at a few merchants. They compare the price of the product and the shipping cost from the merchants. Another item to consider, is that many shoppers also look for free coupon codes to get free shipping or 10$ off from a merchant.

What I do like about your idea is that the prices are checked via crowdsourcing.

I think your site UI could be a little fresher.
