In our house we totally love the Alien In Underpants books, and right now you can order Aliens In Underpants Save the World for just £1.99 instead of the normal price of £6.99.
My kids never ever tire of this story. I don't know if it's the cuteness of the story itself - it's easy for kids to remember and read along with - or if it's just the fact that underpants always seem to make little boys laugh, but it's the kind of book that means we can always end the day on a high note, no matter what else has gone before.
Plus, if you enter the discount code FREE2DAY you should also get free delivery. I've just tested it on my basket of books and it worked a treat. Time to stock up on our bedtime story material!
The code TODAY25 also takes 25% off and gives you free delivery as well, incase the above doesn't work for you. With that code, it's worth checking out the 10 books for £10 deal at The Works right now too. Loads of bedtime - or daytime - reading bargains!
