ARD needs to make money as a store since it has a physical location as well. The licensing fees from BA on top of that are probably quite expensive, so both of those are going to add up on top of the model production costs. I'm not sure if there are any tariffs to worry about but market speculation might push your shipping costs up as well.
Your only option is to suck up the cost, since no one else can retail these(much to my dismay) or wait for someone else like Gemini or Phoenix to release a BA A380.
Now I am mildly confused about where you got the $114 USD from, £49.95(Unit price for an ARD BA A380) is around $69USD, where are the other $45 dollars going to?
