Save yourself some time and money Rated 5 out of 5 stars

I've found it handy a few times while shopping for goods on amazon, even though use Amazon Prime, some products are just not worth buying through them and this gives me a quick way to verify I'm getting an okay price.

I run with firebug and a few other extensions w/o issue.

This review is for a previous version of the add-on (1.5.2.1-signed.1-signed).
