Welcome to On Sale at FOX Business, where we look at cool stuff and insane bargains.

Barnes and Noble livens things up, while Amazon launches another shopping app. PayPal wants you to pay whenever you want to pay and Blekko goes live next week. 

In Color

Barnes and Noble (NYSE:BKS) has an all-new look for its Nook e-reader. The Nook Color is a 7-inch Android-operated LCD touch-screen device, and has 8 GB of storage with built-in Wi-Fi. (Sorry, still no 3G capability at this time.) 

The device is app-ready, shipping with the likes of Pandora and Lonely Planet. It can be yours for $249. The Nook Color will be released on Nov. 19, and you can pre-order it online now here.

If you can’t wait a few weeks, and still love e-ink, the original version is still available for $149.

Window Shopping

Speaking of color touchscreen devices, Amazon (NASDAQ:AMZN) just launched an all-new shopping experience designed specifically for Apple’s (NASDAQ:AAPL) iPad.

The new app, called “Windowshop” is designed to help users better navigate the products available at Amazon.com using 1-click ordering and package tracking options. Download your free Windowshop app here.

Mobile Payment

Online payment system PayPal just announced its latest payment-via-mobile-device endeavor. It’s called Mobile Express Checkout and can be used with existing PayPal Express Checkout vendors. 

All you have to do is sign in using your PayPal account, and you’ll remain logged-in while surfing the web for shopping deals on your mobile phone. (That means no navigating between various sites while trying to log-in to PayPal to make a purchase.) Java giant Starbucks (NASDAQ:SBUX) is getting in on the action, too, pairing up with PayPal to let its patrons use Mobile Express Checkout to instantly reload Starbucks cards via its iPhone and iPod touch app.

Search Party

New search engine Blekko.com is getting ready to shed its private beta status and go live on Monday, November 1. Blekko has its own search language, using “Slashtags” to help users filter results and find exactly what they’re looking for. Say you wanted to learn more about the latest PayPal app. You’d type in PayPal/news. Or if you wanted to search a particular website, you’d type in app/PayPal.com.

Pop-Up Deals

A new social shopping service, appropriately named “Cheep,” is now available for bargain hunters everywhere.

You have your own personal shopper when you activate Cheep, as it operates via a browser add-on and knows when you’re looking at a specific product on any given Web site. Looking at a new flat-screen TV on BestBuy? Cheep will appear at the top of your screen with a list of price comparisons from around the web to make sure you know what other options are out there and therefore find you the best deal.

Wish List

Looking for the perfect gift idea or trying to find a place to register that gives your friends access to your wish list without forcing them to go to several different Web sites? Try Wishpot

OnSale’s favorite is the Wishpot Daily Deal, which lists everything from furniture to appliances, and finds great bargains from all of Wishpot’s favorite stores. Once you sign up for a free Wishpot account, you can activate price alerts to tell you when that new camera you’ve been eyeing is going to go on sale.
