Amazon.com has the best prices I’ve seen yet on the LEGO® Dimensions starter kit. The price does vary based on what console(s) you own, with the most expensive being $69.94 USD for the Xbox One. That’s still 10 bucks cheaper than I’ve previously seen for just the base kit. A number of the expansion packs are also discounted on Amazon, but I’ve seen better prices on many of them elsewhere, so make sure you look around.
