Essentially, the markup amount is subtracted from the bids that advertisers make before those bids are submitted in the auction. This means that the actual bid entered into the auction is reduced by the amount of Google Shopping’s fee, so Google charges you twice – once as the Google Ads in the action, for the second time as the CSS.
