Amazon is a wonderful store for getting great deals, but it's not always the easiest to browse. Scroll.am makes it a little nicer with a Pinterest-like infinite scrolling layout you can search by category.
You don't need to do anything special to use Scroll.am. No downloads, extensions or userscripts. Just go to the website, pick a category and start browsing. You can jump straight to Amazon by clicking the product and carry out your transaction from there. You can also check out the via link below for more sites that will help out with your Christmas shopping.
