Mom went to the mall to buy a windbreaker, which happened to be a promotional event in the mall. During the promotion period, customers can enjoy a 20% discount when purchasing products while using the VIP card (the VIP card enjoys 95% of the original price). My mother took a fancy to a "passerby" windbreaker with a price tag of 880 yuan. How much can I buy this windbreaker now?
