if you haven't heard of freecycle, do a google. in the last few days I've offloaded a heapload of bricks, blocks, lintols, tiles slates and slabs which are left over from this job I'm doing.
it's cheaper than a skip, easier than the tip, the stuff literally gets carried off your premises to be used by someone else.
yes, you do give it away free, but you can also _get_ stuff for free. have a google and join your local group, you have nothing to lose but your old unwanted tat ! LOL
