Toys R Us currently has the Star Wars Sandcrawler (75059) on sale for $249.99 (was $299.99) and I highly recommend picking it up at this price as you should not ever find it cheaper. Lego instituted a policy last year stating that exclusive sets and hard to find items (basically any set over $150) will not be discounted by Lego any retailer.

I imagine that Toys R Us will eventually have to mark the set back up to original retail purchase price or risk upsetting the Lego Group for going against their policy.
