Oh, how I love to comparison shop. Of course, I have my iPhone stocked with apps to help me compare prices while on the go, but if I'm planning a purchase ahead of time, I like to check PriceGrabber to get the best deal possible.But what sets PriceGrabber apart from most shopping websites is its dedicated eco-friendly section called ShopGreen. You'll find the same great deals you'd catch on PriceGrabber, but all the items are green and made from sustainable products. Even better, ShopGreen donates 5 percent of your purchase price to a charity of your choice. Finding what you want, and helping the environment all in one place? Count me in!
