Buying a micro-SIM in UK

[True Believer]

Does anyone know if UK providers sell micro-SIM's only? No contracts, just pay-as-you-go?

Can I buy one at Heathrow Airport on arrival?

no you have to go to a uk carrier store and buy it they sell them. at the air port they sell them normal size sims, infact o2 give them away at the air port pay as you go but normal size
