I buy second hand books, when they are in good condition, there is a fantastic very large second hand book shop in Great Yarmouth, when we when at Easter, went there and bought about 15 books, all the books are 90p each.
In Luton we only have WH Smith and paperbacks are normally £7.99 which are quire expensive, if I do buy new books normally buy from Amazon as they are a bit cheaper than the shops
