Have tried this myself so I know it works. Cravendale are running a rewards programme for free kitchen collectables which includes a tea pot, bowls, tea towels etc.
When you have got enough codes to redeem and have ordered an item you can set ANOTHER account up (register as a new user and still use your address details) with a different email address and it will give you four extra reward points in the following way. Firstly reccommend three of your friends to get three points and then use the following code to get an extra point:
If you are struggling to set up email addresses just use hotmail etc and this will work everytime. I have tried this myself and have received the tea pot, bowl, spoons, tea towels (we use alot of milk) and am waiting on two tumblers and one more bowl!
You can do this after every item you have ordered. Happy collecting.
