Hello  . So the advert states buy 2 and get 2 free , add 4 to cart . But when you add the four to the cart, you are not getting the deal . What’s going on ?

Is this an eBay promotion, or an ad by a particular seller?

It's hard to help without knowing any of the details. Can you post the item number?
