There are nearly 1000 items in the Summer Clearout.
All have an extra 20% automatically taken off at the checkout, then use code FREEDEL to get free standard delivery too.
This means you can get stationery from 47p and books from 79p including home delivery. :)
As usual I was looking for stuff for the kids, and found some activity, colouring and reading books for 79p each to keep them busy, but you do have to be prepared to wade through some very odd stuff to find the goodies!
If you don't see anything in the Clearout section the free delivery code can be used on anything on the site.
It also works with the other multibuy offers they do e.g. 10 Kids Books For £10, 6 for £10 Fiction Books, 6 for £5 Mr Men and so on.
You can only use one code at a time though, so if you're doing a big order one of the other codes might be better for you. :)
EDIT: FREEDEL code expired 28/07/14. Extra 20% off sale still valid, free delivery on £10 spend with code DELTEN.
