Thanks for your reply. Yes, it is the commit-to-buy pop-up which is presented right after payment is final. You get only three options at that point, close the tab, click the x-box, or commit-to-buy. I think if you just close the tab eBay will not get their money for presenting this crap. If you click the x-box it means you have "read" the "proposal" and eBay makes money off harassing you. This behavior just started in the last three weeks or less. I buy something every week from eBay, sometimes every couple of days so I am am good customer, I do not sell, just buy.
For now on I will do a screen capture of this crap and then close the tab. I need a place to post the screen captures of this harassment, only bad press stands a chance of stopping this behavior. Amazons prime games on checkout are almost as bad and even after the Justice Department filed against them they just kept going. Like the other post/reply said I just need to find other places to buy stuff.
