Another decent offer code from the Book People, use code FOXDEL to take £5 off a £25 Spend & Free Delivery too (combined discounts worth £7.95).
Code works on Multibuy offers too, just as long as your basket is £25+, it takes £5 off & gives Free Delivery On Kids & Adults Handpicked Favourites in fiction / non fiction & gifts / stationery.
I used it to buy the fab 15 Book Roald Dahl Collection (£21.99) & the Roald Dahl's Plays for Children Collection - 5 Books (£5.99) for just £22.98 Delivered but there are so many options to choose from, however the best value for the code is to stick as close to £25 as possible as there are often 20% codes around that would take more off higher value baskets & poss give free delivery as long as your basket was over £25 after discounts.
