Time is running out on the Apple Card sign-up promo that began last month. For three more days, you can effectively receive AirPods Pro 3 for free when you sign up for a new Apple Card, but there are some strings attached. If you sign up for and are approved for an Apple Card for the first time, and use it to purchase AirPods Pro 3 by June 15, you can earn up to $250 in bonus cash back over a 10-month period if you meet minimum transaction requirements.
