How does it work?

1. Earn points every time you shop

100 Oryx points = 1 euro

The points you earn from an order will appear as Pending assignment in your customer account, and a few days after receiving your package, they will become Available to use on your next purchase.

3. Redeem your points on an order

You can turn your accumulated Oryx points into discounts on your next order using the same registered user. During the checkout process, you will see the euro equivalent of your assigned points listed as available. For each order, you can choose to apply the discount or continue accumulating points for future purchases.
