Why is there a gift box blinking?

The blinking gift box indicates Keeper's consumer referral program, which allows existing users of Keeper to refer their friends, family, or colleagues to sign up for a Keeper account. When someone signs up using the referral link, both the referrer and the new user are rewarded. The referrer receives a free month of Keeper's premium subscription, while the new user receives a 30% discount on their first year of Keeper. This referral program is a great way for existing users to share the benefits of Keeper with others and earn rewards in the process. You can find more information about the referral program here.
