Please bear with me before reaching for the cold button.
Tesco currently have the above 2D titles available for pre-order at £ 15 each (more than Sainsbury's I know). However if you buy more than one of them then it takes you over the magic £ 25 which allows you to get a 15% discount using 15OFF25 taking the individual prices to £ 12.75.
However, what makes this deal so good is that you can ALSO use code DVD250CC and get 250 clubcard points for each Blu Ray you buy. These have a face value of £2.50 but are worth up to £ 10 in rewards if you use wisely. I have tried and successfully used both codes together.
In addition the probable £ 1.02 Quido makes the real cost of each of these pre-orders less than £ 10 each (or a nominal £ 1.73 if you max CC value)
Avengers Assemble also available for 84p more.
Other titles and 3D versions also available but unless you use the CC points for rewards they are not such good value.
