There are no excuses now.
No: "Sorry I missed it"... "My video store doesn't carry it"... "I can't afford a box set"... "I just don't like you, leave me alone."
Season Two of Robson Arms is available through Apple's CanadianiTunes store. Just a $1.99 per episode.
As a bonus you can see the writers'(and producers and directors) credits in the free preview available on the site.
