The invisible hand
We always want to find the lowest prices. It doesn't matter where you shop. Online we look through a lot of websites trying to find where we can get the best deal. There is a Firefox add-on that i love. Its called The Invisible Hand. This add-on pops a bar on the top of your browser displaying where you can get that product cheaper. It doesn't matter what site you are on. It will search, compare and pop out the lowest price. Try it and let me know what you think. Here is the link to download it.
Difficulty Level: Very Easy
