Wow! This works so great! I've just tried it, loved that it also suggests better brands to look at. It would be great if you could do the same for amazon.co.uk - it's basically the same amazon but we use it in the UK. This looks awesome, maybe you should try posting it on Product Hunt or some reddit threads? It's great it's free so people will be eager to try it.

Thanks for the feedback! And yes, I'll include Amazon UK support in the next release. I also plan on expanding the "suggested brands" to the search page. Yes, I definitely need to do more research on getting visibility to the extension.
