My cousin sent me this link yesterday, saying I would like this ad and to not click on any of the products but just wait for the process on the page to develop.
She was right, I thought the ad was great. It's for a store in Amsterdam, and is in dutch - but it doesn't matter if you can't read dutch. It was useful that I had my computer sound at a high volume.

I couldn't guess if this helps the store sell more or less of its products, but I might check the store out if I were ever in Amsterdam..
