I have tested these promotions and they don´t help in sales. Reason is a weird search algorithm on CGT. Had a discussion about with CGT but they show me different search results than I see when searching for models, even if we search via "Best Results", thus "exact search", thus the only what a potential buyer is using when seraching for a SPECIFIC model. So, promotions will not override their weird search algorithm and that´s why they are pointless.
It would be better to make things better, to improve weaknesses, such as the weird search algo, as to provide new "features", that don´w properly work due to these weaknesses. Pointless.
Don´t care about the promotions anymore, it´s just eyewashing and distraction from problems on CGT.
