sounds like UK is waiting for tyre shipments to arrive,
yeah not as cheap as camskills but they are the closest in price. others are even more i think, or don't even supply them. i think black circles did them, but mytyres don't. might be worth a try.
other option is to wait till feb if you want them, how critical are your tyres at the moment; some tread; or no tread?
i'm not on commission, wish i was just found something that works very well on the zed and doesn't cost a bomb. you should like them, not heard anyone get them and not like them so far.
