I was searching for the other Little Mermaid films for my daughter's Birthday and came across lots of Disney DVDs reduced on Asda Direct. I know Tesco have their own online promotion but thought this might help someone. They seem to be listed under different categories so you may have to search for them individually. Some ones I found are:
Winnie the Pooh £3
The Sword in the Stone £5
Peter Pan 2 £5
Little Mermaid 2 £5
Little Mermaid Ariel's Beginning £5
Loads of others are reduced to £7.00 e.g The Jungle Book and some Blurays are reduced too e.g 101 Dalmatians £7.50.
