On the keywords page of an Amazon PPC campaign, match all bids – or go to the next page if all bids are already matched.

match-bid.js

document.body.style.background = '#fff';
var links = $('a:contains("match bid")');
if (links.length) {
  links.click();
} else {
  var next = $('.a-last a');
  if (next.length) {
    next.click();
  } else {
    document.body.style.background = '#fee'
  }
}
