I've had lots of success with Trade it or e-bay.
It's not all used slabs - lots of people over estimate and sell the exes on cheap - as long as your not in a hurry and don't mind picking them up.
For some back story my wife and I bought this ex 1930's council house ~9 months ago and spent the summer doing the interior. Now that it is summer (and the inside is finished) i finally get to work on my garden
Being a novice at pretty much everything DIY prior to buying the house - i figured...
This is about 1/4 of the bushed that were cut down - most went to the local tip - the rest got burned.<br><br>The pile goes from the back of the house 30feet straight down to the other end of the garden.
After cutting and burning the bushes that ran from the left hand of the pic all the way to the bomb shelter.<br><br>Grass was ~3 feet deep - trimmed with a hedge trimmer down to ~4 inches.
