Toys R Us has introduced up its annual Big Book catalog of toys — on Facebook, in a new application developed by Context Optional. The application has its own tab, requires users become a fan of the Toys R Us page and allows fans to browse through the 80-page book filled with deals and discounts on toys, games and more.

The Big Book includes deals on hundreds of popular items found at Toys R Us, Babies R Us and through the companies’ affiliated online retail sites. The application also gives users the ability to shop for the items they find, with a link to the Toys R Us site to complete the actual transactions. The Big Book can also be found on the Toys R Us site, where anyone can shop the early deals without needing to become a fan of the Facebook page.

Anyone browsing the Big Book can also share their favorite deals on their walls and news feeds, and there’s a message that can be placed in news feeds when users initially become a fan of the page through the application. The application is more or less identical to the weekly ads that can be found on any number of online retailers’ sites. Developer Context Optional is no stranger to helping brands with campaigns, creating Facebook applications for everyone from Kraft to the Travel Channel.

The application is obviously aimed at enticing shoppers to spend early for the holiday season, with deals and discounts valid through Nov. 26. The company will more than likely be dropping prices even further on select items for Black Friday, but the move is designed to give shoppers an early option to pick up gifts this season. This is probably just the beginning from online retailers, and we expect to see any number of deals and applications on Facebook as retailers attempt to extend the holiday shopping season to help recover from slow sales this year.
