Much to our delight, Lego is constantly launching cool sets—like this new Nightmare Before Christmas display or this Jaws boat —but like any limited edition release, they’ll likely only be available for a short time.

Available at Amazon, the Lego Dungeons & Dragons Minifigures (item No. 66765) set — which is listed in the top five “ Best Sellers in Building Toys ” category on Amazon — features six random characters for your next D&D campaign play. It’s priced at $29.99.

Some of the very best LEGO Star Wars sets available also happen to be some of the most expensive LEGO sets you can buy, so it's worth watching out for sales when they come. Amazon is having such a sale this week, and we went and gathered the best deals on some pretty awesome Star Wars sets happening right now.
