Re: Channel 9 show last night (Tuesday)

As we dont have the facilities to record at school, I get all my tv shows from Enhance tv. They dont have to be super recent either. They usually make the dvd and deliver within an week and at a reasonable price.

My glassware is in the cupboards nearest the sink and dishwasher so i dont have to carry it too far. ...
