can quite easily create the label by inputting the address manually if ebay is a bit slow in updating the info to the click & send site. As for the wrong suburb problem it is often the buyer's fasult as they have input the info as North Anywhwere instead of Anywhere North or there are several suburbs with the same postcode so C&S just need you to confirm which it is.

Instead of getting thrown back at the end I always click on validate so I can sirt out any problems there and then.
