Instructions:I received this through the post today - a free 5GBP voucher for jackpotjoy.
If you already have an account - go into promotions, then select "claim a voucher"
You then have to input your username and email address, and voucher code - WCP-2734158-5. You will then have 5GBP credited to your account within 72hours.
I don't know if this will work for everybody, as I was sent this through the post, personally........but it's worth a try !!!!
