Thought it was worth mentioning that these codes now work on SALE items too.
2724 saved me £10 on a £20 spend plus free delivery
0934 saved me £8ish on a £29 spend (so not just 50% off favourite item as posted)
1174 saved me £10.17 on a £29 spend (including the FREE p & p)
All credit to the original posters - thank you very much- just thought it was worth posting as these codes rarely work on Sale stuff.
