Yeah I report these all the time whenever I come across something that interests me but the seller has over-inflated the postage costs to make up for the lower sale price.

I remember when I was looking around for a Unicron, I saw one listed for USD$9.95 as a Buy It Now price, however the postage cost to Sydney was USD$90

Needless to say, I reported it and eBay cancelled the listing - it eventually was relisted a couple of weeks later at USD$90 inc free shipping.
