I'm trying to buy a tumble dryer from Dixons and I want to use the TUMBLE4 code to get 4% off (as advertised here: http://www.dixons.co.uk/martprd/editorial/aff_dev_affiliategoogle_kitchen)
but when I add it at the checkout is says
"The voucher number you have entered is incorrect please re-enter the number. "
Am I doing something dumb or does everyone get this error?
Cheers for any help...
