Are registration to the website and subscription to the newsletter the same thing?

No, they are two different things.

Registering to the website is a requirement to place orders on www.lesacoutlet.it

Subscribing to the Newsletter is instead optional. By subscribing, in addition to always being up to date with our news, you will receive a welcome discount code UP TO 15% (• EXTRA 5% on already discounted products • 15% DISCOUNT on the news in the Collections section not on offer.) that you can use when finalizing your order.
