I looked for this boxset a couple of months back and couldn't find it anywhere. Ended up paying £30 for a second hand set on eBay (though that had 50 books, not 48). This is a good price.
Bought this one and the little series for 13 each from the works a while back. The Mr men boxset I purchased had 52 books included so not sure what this one has missed out... Maybe Walter the worm and Mr Christmas and two others
Bought this from the works for £15 while back, note it's still that price but OOS. Quick search found WH Smith selling this now for £191 lol. £30 is not a terrible price, but I would wait for one of the discount book sites to restock
My first one was Mr Muddle.....he's my hero!
