Historically, LEGO has had a 10% discount online at their Shop @ Home website on the Black Friday weekend.
ALSO, if you go to a brick & motor LEGO Store, they give you a card when you checkout and it has at least a 10% off and maybe more … it could be as much as 50% off!
Anyone can get these deals, you don’t need a VIP card etc., just a method of payment.
