Just been to load the van up for the month and CTD have Ditra 30m rolls for £215.94 (inclusive of VAT) I'm pretty sure that's the cheapest in the country. Just incase anyone needs any in the near future.
bri nearly the cheapest . i get it for £ 8.94 less for 30mts roll but i do have to buy min 3 rolls and have an account ,so for one off roll that is the best deal i know of
