Boxing Day sales are never usually the best when it comes to LEGO. The retailers probably assume that most LEGO purchasing happens before Christmas and people won’t be interested afterwards. That doesn’t mean there aren’t some sales.
Amazon is getting in the boxing day spirit with a sale on a bunch of sets that they probably just want cleared.
It’s a very random selection, with themes such as DOTS and Star Wars and even some Friends.
You can check out the selection for yourself here [affiliate link]. This offer might change over time so it’s probably not a bad idea to check back regularly.
