Good value black weed-suppressing liner?

[Storm]

We've finally come to the end of our 50m roll of weedex-style black weed suppressing liner.

I remember trawling for hours on line to find the best price for a roll.

Has anyone bought any lately and found a good deal for a 50m (or longer) roll?

my friend is an upholsterer - they use the same fabric on the underside of sofas - i get it in a 100m x 1.5m roll for about £35 ....

Wow!! That's good. Where can I get that? I don't know any upholsterers
