Looking for a present for my 3 year old and saw a 7" gruffalo in WHSmiths for £16!!
Found this online which is a bigger 9" version, and cheaper than the 7" one too.
There are a lot of other 7" characters from the books too at a bit more (around £8?) but they're not discounted as much so doubt they're that great a deal.
PS - Camelcamel suggests this deal is also the cheapest it's ever been on amazon (just).
