I've had a quick browse and can't see that anyone else has posted this - so, as my title suggests - there are cheap DVDs, PC games and CDs in Tesco atm.
I got Titan AE (sci-fi cartoon film - ds1 likes it), Willow, and Educating Rita - all for £2.97 each. And I got a couple of Lego PC games (pre-school, educational letters/numbers/shapes games) which were 97p each and are keeping ds2 (4) amused. And ds1 persuaded me to buy a DVD of 50 Greatest Goals for 97p which he enjoyed a lot.
Here's a few of the DVDs and CDs but there are lots instore and I think the offer finishes on Sunday \link{http://www.tesco.com/entertainment/browse.aspx?Ntx=mode+matchall&N=6&Ntk=P_HIDDEN_Special_Id&Nr=293&Ntt=3832&showall=1\DVDs}
