I've been looking for some good sticker books for holiday trips and Usbourne have always been tops. I spotted a Boys Colouring and Sticker book RRP £7.99 (sold at Amazon for £4.71) for only £1.99.
This book has 48 pages and over 200 stickers. Enough to keep the kids busy. My boys love books like these as they can use them afterwards to either read or and re-stick the stickers. This book has 3 sections.Farms, Castles, and Trucks and Diggers. Just what young boys love.
Now the only issue buying from ChoicesUK is the free delivery requires you to spend £2.50. Luckily for me I wanted two books. But if you only require one book I'm afraid you'll have to look around for something to bump the order up. However there are some great books for 99p upwards. I can recommend http://www.choicesuk.com/Product.aspx/the_tale_of_peter_rabbit_1421163. Even if you give the book away £2.98 is still cheaper than the next cheapest of £4.71
The Girls version is also £1.99
