Wholesale prices are available to everyone in the UK so long as your parcel includes at least three books. The downside? There isn’t one.
For individual copies, try your favourite internet bookshop or order from your favourite bricks-and-mortar outlet. Or don’t use your favourite one. Any one will do. Just, buy the book. Look, in any case, you’ll probably need more so you may as well buy in bulk from the outset…
This page should allow you to buy approximately the number of Bananas you need (so long as you need 3,4,5.10, 20, 30, 50 or 500 copies). Sorry it’s a bit crude but note that you can order 100 Bananas by simply ordering 50 twice. If that’s all too complicated or you need absolutely definitely need exactly 175 copies (for example), please email. The price (normally £6.99) starts at £5 each for 3 copies, and decreases again at 4, 20 and 500 copies. Postage is free in the UK.
