I think special offers are not really advertising.
I view advertising as something brought to my attention that I wouldn't otherwise buy. Being made aware of special offers is more to tweak the moment of buying stuff I was going to buy anyway but waiting for a decent price.
If I go to MediaMarkt and there's a signpost at the phone area saying "Samsung S25 100 euro discount" then I don't think this is advertising. After all the S25's are lying on the shelf right there whether the offer is there or not. I am there to at least consider buying one and I am there already looking for one before I saw the sign, it's just a notification that the price is low.
