Abandoned Cart app tracks who is shopping at your store, and then goes to another tab. Your store tab then starts blinking, attracting a customer to come back. When they click the blinking tab, and go back to your store they can also optionally see a custom message, that can say e.g. "Your cart will expire soon", or "Someone has placed an order on one of the items you have in the cart. We'll keep it for you for 10 minutes". "Checkout within 10 minutes and use a discount code Spring to save 10%"
