Why can’t I find any Coconut Cream Rumchata in the UK?

(Throwing a pic of it in just in case)

Ok so for reference, I’m from the USA and my buddy is from the UK. We have a thing where we watch “Too Many Spirits” online together and drink the same thing. Well I enjoy Rumchata (OG and coconut flavor) and I wanted to buy some for her for her bday. We have eachother’s addresses and all, so I was going to order online since she couldn’t find any in stores near her. I have been searching high and low online, and I cannot find a trace of Coconut Cream Rumchata that’s in England or can be delivered there, only the original !! The reason I’m searching for coconut specifically is because she prefers coconut, lol. Anyway, I’m just genuinely curious and baffled as to why I can’t find it anywhere !! Any answers are greatly appreciated !! Much love! <3 (Sorry for any formatting problems, I’m on mobile currently)
