I just released a new app for the Mac that makes it very easy to search multiple websites at the same time and set up your favorite categories for websites. It's called "Web Quest Surfer" and it in the Mac App Store at http://itunes.apple.com/us/app/web-quest-surfer/id492597830?mt=12 for $1.99. I wrote this app to save everyone time when searching for the lowest price for an item, or actually for any kind of search such as new DVDs, science research etc. I will be continuing to improve it and add features which will go out to anyone who purchases the app. Video demos are available at http://webquestsurfer.com Thanks!
