Long Delay (about 12 seconds) near end of Page Load

On almost every page load, my browser spends tens of seconds download content from store.arduino.com after the page has apparently loaded and displayed. Usually, I will finish reading the page and close it before the store content has completed downloading. This behaviour started when the site was overhauled and appears to be an attempt to maintain a 'shopping trolley' state while we are in the forum. That is IMO pointless and misguided. I don't need to post forum messages while I'm shopping and I don't need to see the state of my shopping trolley while I'm accessing the forum. The two activities have nothing in common and should not be carrying each other's baggage around.
