i got the other one as well and was getting annoyed with them keep reminding me i aint used it and i just recieved this one and wont be using it either
i got one recently too, i haven't used it but haven't been pestered with any other follow up contact from them.
i haven't bought anything for a couple of years i don't think, i did have a peek at the website after the voucher came, but with the high p&p, the couple of things i might have been interested in could still be bought cheaper elsewhere!
