One of my favourite sections of ecogamer is "store feedback", mainly because it's allowed me to make purchases at stores I was unaware of and expanded my choices when it comes to importing games.
However, I think it would be informative to have the shipping/postage costs these stores charge as I have seen a few messages in the shoutbox asking this. Myself included. I can get the ball rolling by providing shipping costs of a few of the sites that I have collated and used. If I have made any errors, feel free to correct them or please add other stores to the list.
