I don't really remember how I came across shopstyle.com, but I have been using it for years. Shopstyle is a site that lets your search for clothing in a certain style, size, price range, color, or sale price from TONS and TONS of stores online at once. You simply browse through the search you made and when you find something that you like, you click on it and shopstyle forwards you to that item's site. It enables you to shop for a little black dress (for example) at Macy's, Express, Ann Taylor, Target, Bloomingdales, etc. all at ONCE!!!
For instance, say you are looking for a dress, that costs between 25-50 dollars, in a size 4. You want a bright color for spring. You can choose the price range and size criteria and then click on as many colors to search for that you want. You can even search for a really good deal on a dress by choosing a percentage off-say you want something that costs less than $50 but is at least %50 off...so the dresses original price would have been at least $100 to begin with. You can do that too!!!
Shopstyle is especially great if you are in the market for something specific. I urge everyone to try it out!!!
