Update: Item is now out of stock. International shipping is also not available.
This set only came out just recently and ThinkGeek.com USA already has it discounted! LEGO Superheroes 76003 Superman Battle of Smallville is currently on sale for $39.99 (reg.$49.99). Use coupon code SKYLAB to receive an extra $20 off $60. Coupon expire midnight EST on May 16. Thanks to forum member tremere for the heads up.
So basically, if you buy two of these sets, you can get them for $30 each (reg.$49.99) which works out to be 40% off! Of course, you can also purchase other items from their site to hit the $60 mark as well. The only key issue here is that you have to pay for shipping.
International Shipping Available: Surprisingly, shipping rates to Canada and the United Kingdom are only a bit more expensive compared to shipping to the United States. All other countries however have significantly higher rates.
