My latest contribution to the Google Chrome Store I think is the most broadly useful tool I’ve developed. It allows you to execute searches on multiple websites at the same time. This can be useful if you frequently search sites like Amazon, Walmart and Target for the same thing such as “Tables”. With this extension you just punch in what you want, and it launches searches on the websites you setup.
