I always message Keith (not his actual name but the name he goes by) before I buy anything, he list's stuff he doesn't have but has access too as he will just pop along to a shop that's local and then send it (not the best way of working admittedly) He is however awesome for dropping prices if you go on his ebay store and make and offer, as long as it isn't taking the piss he generally accepts anything, I also trust his ebay store to be more reliable as to if he has it in stock rather than the website. I've got some cracking deals from him in the past and if there's something I cant get hold of you can also message him and he'll go and find it for you!
