Have you tried Graham at TVS as he has a lot of conway spares, and is very resonable with prices for shipping, ring him as you will get better response than emailing. We use him a lot at conway pwners club.
Thanks Val ,but a pack of six on the penine site £1.66,but with shipping £15 and Vat on top makes a grand total of £19.58 WOW.
The postage rate is variable...the £15 charge is a maximum. They say they`ll email the exact carriage charges.
Having said that, I wouldn`t order anything from them (unless totally desperate) now that you`ve brought that page to my attention. I`ve never seen anything like that on a web ordering page before. Somewhat of a liberty, I feel!
