Green Metropolis provides a market place for second hand books at which one may both buy and sell. As a buyer, one pays a flat fee of £3.75 per volume. Delivery is included in this price unless the book in question is a hardback.
As a seller, one lists the books of which one wishes to dispose on the website. When one's book is seized upon by an enthusiastic buyer, one dispatches it post haste and one's account is thereupon credited with the sum of £3 by the good people at Green Metropolis. One may either set this credit off against the cost of one's own purchases from the site, or request that the money be paid into one's own bank account. (The site is keen to point out that, for every 5 books one sells, one could buy 4 new ones.)
Green Metropolis donates 5p from every book sold to the "Tree For All" campaign run by the Woodland Trust. (A total of £1,974.50 was donated in 2005.)
This is certainly not the cheapest method of acquiring second hand books, and the stock is nowhere near as extensive as that held by, for example, Abe Books. It is with regret that Lady Bracknell is forced to conclude that it would not, after all, be practicable for her to sell her own books through the site because she is often insufficiently robust of health to venture to the Post Office for long periods.
Nevertheless, Green Metropolis strikes Lady Bracknell as being a most worthwhile venture, and one about which various of her regular readers will have been intrigued to hear.
