Buckfast and White Cider

[OpusXKC]

So in my adventures I have recently heard of a concoction known as "Lurgan Champagne", which is an UK drink consisting of Buckfast Tonic Wine and White Ace Cider mixed together. Buckfast, I've read, is a 15% abv fortified, caffeinated, wine, while White Ace Cider is simply a made from apple concentrate 7.5% abv hard cider that you can acquire in a 3 liter jug.

My problem, being in the states is finding the required ingredients. Online is not truly helping as the cost is prohibitive. Anyone have any idea as to where one can purchase these products, or a reasonable facsimile of such?
