Debenhams have in their online sale a 30cm non-stick Tefal frying pan for only £4.80 - a bargain at that price considering its reduced from £16.00. However, use the following codes and you should get a further 10% off and free delivery making it an even greater bargain at only £4.32. (Thanks to Money Spinning and mpadc for the codes)
PGDP - 10% discount (expires 30 December)
SHA1 - Free delivery
I guess I should point out I've not tried buying with these codes as I don't need a frying pan, so best of luck and hope it works.
