Hey Mitch,
Bespin duel was originally supposed to be a limited time set on LEGO.com exclusively for U.S. and Canada.
Recently however they sometimes still accept backorders here in the U.S. (I’m not sure about Canada). It’s no longer sold at Target (at least here it isn’t). From what it looks like, it’s very true that this set is very limited and very exclusive. I don’t think it’ll come back from official LEGO website ever. But, I could be wrong and I hope I’m wrong!
Best bet, if you do have access to these sites: Bricklink or EBay (please be careful of scammers and don’t buy for a outrageous price my friend) I’m sorry if you are having any trouble on getting access to this set. It ain’t right for LEGO but it’s on very high demand at the moment. I hope soon they release in Europe! Stay safe.
Sincerely,
ChefDD
