The number of advertised deals on Black Friday is overwhelming. There is no easy way to compare deals for a specific product across stores. The Black Friday Sites do a good job of categorizing and analyzing the Black Friday circulars. One of these sites called TGI Black Friday has now gone a step further and released a surprisingly useful Black Friday App for the iPhone.
For instance if you want to find out which Wii Bundles will be offered on Black Friday. You just search for "Wii Bundle" on this iPhone App and you see at a glance all Wii Bundle offers with prices available in the different stores.
When you search for iPod touch you can easily see that Walmart has the best deal with $195 and a free $50 iTunes card.

TGI Black Friday announced the free Black Friday iPhone app today and I just downloaded it from iTunes.

This app allows you to browse over 8,000 deals from all the major retail store's Black Friday ads. You can search across all deals and categories. You can save the items you want to buy on Black Friday in a personal shopping list.

TGI Black Friday was developed by the parent company DealCatcher.com.
