I had all sorts of postcode issues when I first used C&S: it felt like I spent two half-days on their support line, but they are very good.

One issue was that my OWN postcode was upsetting the system: I had my own address as Suburb-city- suburb postcode. The beast was happier with me after I removed the city bit and just left suburb and postcode- I had to change it in my eBay profile, because that's where C&S get it from.

The phone number for their help line is on the back of the satchels, and they answer pretty fast. Not like calling Centrelink !
