If you buy on a regular basis since LEGO Store Italian official there is a good chance that you are already a LEGO user VIP. The registration, in any case, is free, and once you have created your VIP account you can also use it in physical stores, not just the Italian ones. We even used it once at a LEGO Store in New York!
VIP points can be spent not only on redeeming rewards of various kinds, including exclusive sets or other collectibles, but also to take advantage of discount coupons on future purchases. With the Boutique Hotel for example, you would receive 3,000 VIP points, which you can convert to a € 20 discount on your next purchase. To join the LEGO VIP program take a look here.
