Yes I know I probably shouldn't have, but when you see lovely Blue Faced Leicester tops at £8 for 500 grammes you just have to don't you? This was from Laughing Hens.
I also found a Finnish stand called Piiku selling fibre mainly aimed at felters. They had batts of fibre, spun yarn, fine pencil roving and sheets of machine needle felt all in undyed and multiple dyed colourways.
I bought 2 metres of the needle felt which is at a stage I think of as pre-felt (ie you can finish it or pull it apart still).
I also bought a big cheese of undyed pencil roving (see pic above with bfl tops) - I've had a small amount in the past which I made a lovely sample from, but have never found the same stuff again to make an actual 'thing' from - so now that I have it would have been completely potty not to take the opportunity.
And yes - me a yarn maker bought yarn! It was however something I can't make - fair-isle style, self striping, cotton, sock yarn along with a lovely pattern for a little tank top. I shall save this for my next holiday break - I think it would make a lovely relaxed holiday project. It came from Web of Wool who seem to specialize in that sort of thing. I was also nearly tempted by a lovely bamboo/soy yarn which was only a little more expensive, but it was only self striping not self patterning so (with a little difficulty) I resisted!
