Agreed to the annoyance by the pop up. I use a tablet to view the site, the pop up blocks one third of the screen, so much so that now the tablet keyboard has appeared it blocks my view of the posting page. I cannot see what I type.
As I go to each new page up it comes again, it is beyond irritating. I do not want to install a blocker (my tablet is old so probably won’t support it anyway) as it is good to know warco have a sale, but not every ten seconds.
