just to let you know i ordered 1200x50x50meters of chicken wire for fencing paid £40-oo for it from this site, i did research and seems one of the better places for prices,
worth a look,

Last month I paid £24 for 20x1 metre :( :(
If you can find a thatcher in your local phonebook ::) they'll give you the old wire they strip off for free :o ;D
