My wife looked at an offer from the Unclaimed Prizes Bureau in Ross-on-Wye which came via a catalogue and was seriously tempted to claim her prize. I am a lawyer and do caution for a living. I read the smallprint which in my view satisfies any legal requirement but it just didn’t smell right. I thought I’d research this a little more and stumbled upon this site. As someone else said “if it’s too good to be true..” Leave well alone it will only end in tears.
