Yeah I was like this

and ready to

one day when I can home and found an express package was sitting on the front step in the rain so I always ask for reg now if possible and happy to pay a little extra for the extra protection and security just incase

and I've found when selling cards most people don't have a problem with it when I explain it covers us both

Proof that I sent and that they received..less

's that way

And if you take note of some of the feedback on
ebay, some sellers say that the person has ripped them off and got a paypal refund and the goods.
I have only sold a few cards on forums and always insist on reg, I would do normal but make sure it's clear that if anything happens they're not covered and I won't replace the card but with reg I'd at least get some money back from au post and try my best to replace it or I'd give a refund but I'd want proof from au post saying YES it did go missing.
