If you click on the link in the OP, you'll see that some statues are 30% off at GameStop. Most of them are Clearance items, so they were cheaper (50% off) in the past and will probably be 50% off again.
Concurrently, GameStop's subsidiary ThinkGeek has its own promo. ThinkGeek stores are a good place to shop if you want to look at the Gallery Unmasked X-23 statue before buying it.
