As a buyer I too use too think that the postage cost's of some seller's was high but as a newbie seller I came to realise that most of the time they were reasonable. it takes time to wrap and pack not to mention the trip to the post office then the postage itself it all cost's money.

As for a buyer's/seller's rating who really cares about the score (unless it's really bad) it's the feed back that counts and how the other person has reacted to it.
