The results and analysis for Blu-ray (and DVD) sales for the week ending 31st August 2013 is in. The Great Gatsby was the week's best selling Blu-ray title, in a week that had 5 other new releases in the top 10.
An intersting thing happend with regards to the S3 boxsets of The Walking Dead and Sons of Anarchy. Both did less well on Blu-ray than compared to the S2 versions of these shows (the same week) last year. This could mean that the DVD version sold better than expected, or that the Blu-ray version didn't sell as well, but the reality seems to be that more people chose to buy the DVD version this year than compared to last year. The reverse is usually true.
