OP

Quoted from swinks:

I even sold some drops to wolftownjeff yesterday before all this happened and he paid the required amount in USD and not in AUD which effectively $70 too much. I could of sat on it but I could live with myself. I refunded him and he paid again the correct amount in AUD and saved himself $70AUD. This has happened many times as paypal defaults to USD and on every occasion I refund and get them to pay again - with many people being really appreciative.
I would never do this as is criminal if I were to do this and would destroy my reputation.
Australia has increased there declaration control recently and scan many packages to ensure the contents are correct so would be surprised if it happened in Australia but obviously stranger things have happened, so can't remove that possibility. Waiting for more details and photos to start a postal investigation at my end - strangely no photos after 8hrs of asking - this would be first priority if it happened to me.
