I don’t usually do deals but Amazon has a pretty good one going on right now with a BOGO 40% off sale on select toys including LEGO sets from various themes like Star Wars, Lord of the Rings, The Hobbit, and Castle. Add a set to your cart and another of equal or lesser value and that one will be 40% off. Some of the sets already are already discounted so you’ll be getting a better deal.
One good deal is the LOTR Pirate Ship Ambush (79008) which has a discounted price of $82.50 and if you buy another one, you’ll be saving $33 on the second one making your total $132 or just $66 each. This is a pretty good way to build up your collection of ships. Another deal is the LOTR Battle at the Black Gate (79007) where you can have a full gate just like the film.
