Green Metropolis

Whether it's the latest release or last year's bestseller, all our books sell for one unbelievably low price of £3.75 and all standard paperbacks include FREE delivery. We also pay £3 for every book you sell with GreenMetropolis.com.

By recycling used books not only are we saving existing trees, we're actually planting new ones. How? GreenMetropolis.com donates 5p for every book sold to the 'Tree For All' campaign run by the Woodland Trust
