LEGO Shop@Home now has the Toys'R'Us exclusive 7879 Hoth Echo Base
on their site available for ordering. It'll cost you $89.99, five bucks cheaper than TRU, and you get VIP points. It'll still cost you shipping since their free shipping promo ended a little bit ago, but you can still get the free Kingoms polybag set to help ease the sting.
Thanks to Jon for the heads up.
