Thanks for that .... I have bought a couple ready for my hols. Probably selling off the old series now that a new one is ready to go .... mistakes and all!

Try also a supplier called Above and Beyond www.aboveandbeyond.co.uk

I recently bought Landranger 1:50000 maps at £4.54 each, including free second class mail delivery

Cheaper than OS and much much cheaper than walking up to a visitor centre or high street store.
