The amount of B-Dollar on your account expires every 90 days. Whenever you receive B-Dollar from your visit, the expiry date will be re-calculated for another period of 90 days. 

Ways to extend the validity period of B-Dollar: 

Method 1: 

Make a new appointment for a service and use it before your current B-dollar amount expires. B-Dollar rebate will be automatically credited to your account 2 weeks after the day the service is completed, and the total amount will be extended for another 90 days onward. 

Method 2: 

Leave a review on the order you have booked at the shop as soon as your service is completed. Bear in mind that B-Dollar rebate gained from the review will be automatically added to your account immediately; Likewise, the total amount will be promptly extended for another 90 days onward.
