Trying to comparison shop things on a site gets to be really aggravating. I can't find any kind of back button to go back to the previous page from whichever page I landed on when I wanted to see what the alternative choice was. I guess I used to have a back button built into my phone that my new phone doesn't have and there's no facility in the app for going back to a previous page. Not that there appears to be one for going forward either so if I went back I'd be stuck there.
