The UK transformers shop

Hi guys! So, next Friday i'm Flying to London for a weekend from Italy Just so i can visit the Transformers store... Specifically i am looking for Megatron figures. Ss 86 megs Gamer edition megs Ss 109 Ss 13 Ss 49 Siege or earthrise perhaps

Now i know most of these are very old so there Is Little to no chance of they having any stock. However, to anyone whos been there recently, how Is the selection? Have you seen any of these or others?

Thanks a lot!
