I am not sure if this is free or not as I have not tried it yet, but it says £0.00
I am a bit of a wimp, so I don't want to try it until someone else has had a go.
There is a charge for postage £5.50 (mainland uk)
Worth a try, you can always ask for a refund if they phone/email you and tell you it was the wrong.
Please tell us how you get on if you try it. (BTW, it does say that it is "Coming Soon" so not sure if this will affect purchasing?)
