ShopStyle, an e-commerce aggregate that brings all of the major online stores under one virtual roof, just launched their first iPhone app. Just like the site, the ShopStyle Mobile lets you search by brand, clothing type, retailer or price to find every possible fashion item available in the e-commerce world. Now, you can make sure you're getting the best deal on that discounted handbag or the size you want on those almost-sold-out pair of shoes. What's more you can shop online while you're in the store so that you don't have to lug around shopping bags or ship gifts yourself. It's like GPS for shopping, click on the title link above to add it to your iPhone today.
