Have you window shopped around Amazon, and wished certain things were cheaper, or you know maybe you wanted to save a few items for you to keep your eye on without having to go through all the trouble of opening up a wishlist or temporarily adding them to your cart?

The BuyLater plugin for Firefox lets you do that. It adds a ‘Buy This Later’ button to Amazon Web pages below the shopping cart so you can keep track of prices, sales, and availability. The plugin immediately lets you know when something goes on sale. It checks Amazon every minute, so you know exactly when something is on sale. You can save hundreds of dollars using this, especially if you’re looking for a hard-to-find item, or something that’s on sale for only an hour or so, because Amazon has a lot of those sales.
BuyLater Amazon Plugin
To set it up, you’ll have to go to BuyLatr.com download the plugin, and restart Firefox. After you’ve restarted Firefox a BuyLater Settings browser window will pop up. Put in your e-mail address then click ok. Now go to Amazon and make sure you’re logged in, and go find an item that you’d like to receive notifications about. The BuyLater button should be located right below the Add To Cart Button, and just click the button. Then BuyLater will tell you they’ve sent you an e-mail and just go to your e-mail and confirm it. Now you’re tracking prices and availability of that hard to find item.

It will send you Twitter, and email notifications depending what you specify.

The BuyLater plugin for Firefox will make a good addition to any Firefox plugin collection.
