base.com currently have the Disney blu-ray buy-one-get-one-free deal on.
Includes Toy Story 1 & 2, Alice In Wonderland, and other combi-packs.
I might wait as amazon did this last time too but the price was about £12 for 2!
Also at dvd.co.uk as it's part of the same group.
Thanks to goonertillidie - don't forget quidco too!
