Loyal customers of Blanc get special cards that give them various perks and discounts. There are Golden, Platinum, and Black cards that customers can get based on the amount of money they spend and their status (aka balance on their bank accounts).
The Golden card is the most common, and it requires customers to spend $50k a year on Blanc merchandise while providing exclusive access to new designs and a 2% discount on future purchases.
The Platinum card is for customers who spent more than $100k a year, and it provides the same perks as the Golden card with a higher discount that reaches 5%.
The Black card is offered to customers who spent on Blanc jewelry more than $500k within one year and other than 10% discount, it gives them a chance to meet with a designer and get custom pieces made (the design is free, they still need to pay for the end product).
