Amazon have reduced their cookie cutters again. Small (2" / 5cm) 31p, Large (3" or 4") 76p. This is the price for them delivered.
Hopefully people will not expire once one of them goes out of stock, since many others are available.

For the whole list search for "cookie cutter kitchen craft" and sort by price. I cannot link to the list for some reason, it defaults to the home page. Or see first reply. List added there.
Cutters include: star, holly, bell, angel, etc so ideal for christmas. Also more usual ones like teddy bear, fish, butterfly, chick, car ...
I ordered one yesterday on amazon prime trial, and it was delivered special delivery today! For 31p. They are very solid metal ones likely to last for ages, not cheap plastic.
