Update: It appears that LEGO did not update the promotion yet. You still get 75 bonus VIP points (last month’s promotion) instead of a FREE Mini 40028 Hogwarts Express.
In addition to the FREE LEGO Alien Conquest 30141 Jet Pack polybag set on orders above $35 / £25, there’s another promotion going on at LEGOShop. From August 1st to September 30th, LEGOShop will be offering a FREE LEGO Harry Potter 40028 Mini Hogwarts Express when you purchase 10217 Diagon Alley.
So far, we have word from LEGOShop that the offer is valid for United States, Canada, and the United Kingdom.
