Windows Central App Roundup: Windows Phone Shopping Apps Even though many retailers got a jump on things this year, yesterday marked the traditional beginning of the Holiday Shopping Season. Deals will be popping up all over the place over the next few weeks and there are plenty of Windows Phone apps in the Store that can help you sort it all out. The Windows Phone Store has a Collection of apps to help make choosing the right app a little easier. The Holiday Shopping Collection has a few dozen apps to help you shop online, keep track of those discount cards, find deals and more. We’ve plucked four of the top rated apps from this Collection for this week’s roundup, plus a few that are outside the Collection.
