The LEGO Star Wars Bespin Duel (75294) set went on sale not too long ago and in less than a day, it has already sold out on both the Shop@Home online store for the United States and Canada.
However, Target.com is still listing it and allow you to add it to your shopping cart. I’m not sure they are still taking in orders but it is worth a try if you were unable to get it through LEGO’s Shop@Home.
The set is retailing for USD39.99 and it is only available in North America as it was originally intended to be an SDCC exclusive. I know that LEGO did say that they would not be release region specific sets but I guess this would be an exception to the norm.
