I feel like every holiday season, there's at least one gadget that everyone is trying to get their hands on — remember the instanity with the Wii?

If there's a certain product that you're waiting to come back into stock, but you don't want to have to keep searching Amazon every day to see if it's available, there's a download called Buy Later, which will come in handy.

After downloading this Firefox extension, Buy Later will add a button to Amazon.com webpages and monitors when specific products come back in stock. You will then either receive an email or tweet notification so you know you can get the goods!
