Retailer button and a pop up?

I don’t know what the default behavior is. But, when I click on the amazon button, I can see an icon in my browser address bar telling me a pop up was blocked and the page refreshed. It doesn’t take me to amazon.

If anything odd is done with retailer links, could you consider changing them to normal links? I also see target=_new in the code which isn’t standard. It should be nothing or if you want, target=_blank.
