I too just printed my first label only to discover it was incorrect.  I then cancelled it straight away.  I have been charged for the postage on my account and I'm wondering how long it will take to get a refund.  It seems that maybe Click and Send is still a better option.

Hi, I haven't seen this option. Would you please tell me a bit more about where to print the invoice with gst amount shown? Thanks.

6. Can I get a tax invoice for my postage labels?

Tax invoices are available five days after labels are printed (once the option to cancel has expired). You can access your tax invoice through the Manage postage labels page in My eBay.  

No tax invoice is issued if a label is cancelled (because you receive a refund).
