With the purchase of this product, you will earn Oryx points for your next order

How does it work?

1. Earn points with every purchase

For every purchase you make in our online store, you will earn Oryx Points.

On each product page, below the price, you will find the number of points that will be added to your account once your order has been completed.

100 Oryx points = 1 € discount

2. Collect points

The points earned from an order will initially appear as Pending in your customer account.

A few days after you receive your order, they will become Available and you will be able to use them on a future purchase.

3. Redeem your points

On your next purchase, you can convert your Oryx Points into discounts. During the checkout process, you will see the amount available in euros based on your accumulated points.

With each order, you can decide whether to apply the discount or continue saving points for future purchases. Please note that Oryx Points expire one year after they are assigned.
