Question about Midea Porta Split

A day ago, I received a notice that the air conditioning system suddenly costs 811. A few hours later I click off the offer, and the price is now 969.--, now even 1107.10! The summer is over, demand is zero, how can the price change so quickly? After all, nobody wants to buy an air conditioner that weighs 55kg at a high price and store it for 6 months. Would it be possible to get a serious and attractive price proposal? Many thanks
