Ok, I've costed the postage. If I get the pipe to go into the envelope without doubling up it can go via the large envelope rate. That's £1.55 Second class, £3.30 for First class, First class signed and recorded is £5.30, 2nd class signed and recorded is £3.55 and just 48hr tracked with no signature is £3.45.
Choose what you want to pay and add £12 and send it via PayPal to PimlottKen@GMail.com and I'll get onto it straight away. DON'T forget to include your address and your name, looks odd sending it to a forum name.
I cut all the pipe into 1m lengths and Bryan was correct, got 8 lengths so 8m in total. 5 provisionally sold, 3 left.
