I follow a particular shop here on Etsy and have a few items in my cart. An ad for one of those items in my cart pops up on a page of search results, left side on my Windows PC, that announces a 24% discount. It catches my attention, because it is a better discount than I ever see with this shop. The button takes me directly to checkout, which shows the smaller discount, a more common temporary one for this shop.
I have screen shots FWIW.
