Just received an email from DVD.co.uk saying they have an offer on for 4 DVD's for just £8. My bad maths makes that out to be £2 per DVD.
There are over 3 pages of DVD's to choose from and I will attempt to list the best ones below.
There are a mixture of films available plus many of the James Bond ones that are priced at £4.95 individually, snap four of them up and save quite a bit of money. Many other DVDs are already listed individually at £2.95 so you'll still be saving money whatever DVD's you choose.
