What are you trying to get? A £1 off voucher or a £1 off link? In that post there is a link to a 50p off voucher and a link which gives £1 off DVD's without the need for a voucher. (see point 3. ..."This link already gives a pound off DVD's and 50p of Cd's without the need of a code".. The key word being 'pound')
Well the £1 link is still working fine, as well as the dixons one.
However, it seems the 50p email one is somewhat hit and miss now.
Try as I might, in this case 5 times, I could not get a 50p voucher working.
Still Sex and the city season 4 for £14.49 using the pound link and a spare 50p voucher in the draw, not to be sniffed at
