Uk collectors?

I recently developed an interest in AG dolls So.. As any normal person would do i have made the expensive decision to buy one, the only issue being that i live in the uk which means i unfortunately have to buy it from somewhere else.

I did a small amount of googling and found a website called "my doll collection uk" they seem to sell AG dolls at a higher price? Im just curious is this a legit website? If anyone has experience purchasing from them could you let me know how it was <3 ty
