Jellyfish is a good way to get comparison prices on all sorts of products.  Of course, I use pricegrabber and frugal for that, so why would I need another site?  First, Jellyfish gives cash back on some purchases.  But that’s not the cool part – they have something called “Smack Shopping” which is quite innovative.  You can get more details at an Information Week article, but basically it’s a form of reverse auction, which consists of sellers competing for buyers by offering increasing discounts. For participants, the event involves a web page that features a product and a steadily improving discount that starts at 0% and rises toward 100%.
