Looks like a few price drops at Amazon UK for Blu-rays if anyone is interested. I pulled the trigger on this one and got a few others that came down in price.
You can get the Breaking Bad Collectors Tin Edition for about £10 more here(amazon.co.uk).
Others on sale include:
Warehouse 13 £20.39 incl VAT(amazon.co.uk)
The Matrix Trilogy £7.00 incl VAT(amazon.co.uk)
Falling Skies Set £31.49 incl VAT(amazon.co.uk)
Is the only difference between this and the tin version the tin? Actually no, it comes with 4 extra discs hmm
