You can do everything in the Post Office nowadays. I suppose that’s why they’re calling them Post Shops instead. They sell cards, telephones (mobile and fixed line), music CDs (what’s the point of those year CDs, eg 1970 including hits from 1970? I was born in 1970, but why does that mean I would identify with the music from 1970?), footy mascots, office supplies. You can also pay any of a multitude of bills, get photocopying done, etc, etc, etc.
All of which means I have to wait ten bloody minutes just to buy a book of stamps.
