Ask HN: Idea on Crowdsourced Deal Hunting

Just bouncing a idea around, let me know your thoughts.

* Background: User wants to a buy a product, Laptop XYZ, best price he finds is $1900, wants better.

* Idea/Solution: User visits website, says they want New XYZ Laptop for $1800.

* Internal: Crowd-sourced people or outlets/stores can look at requested product/price and see if they can match it. Someone finds a deal for $1750.

* Finish: The original user gets the product at the requesting price $1800. The deal hunter keeps the difference $1750.

Current issues: How to handle the money/item transaction. One way is for the service it self to charge the difference first before revealing the original deal site.
