I had some vouchers from Kellog's cereal boxes about a year ago...the expiry on them I remember at the time was October 2010
The voucher entitled you to select from some DVDs on Play.com for £1
I used one and kept the other for future use...now its the future and I cant remember where on the website I needed to go to.
I posted on here about them, but cant find the post now
Anyone remember these?
