I thought the club rules were: 100 used stamps, no duplicates & no damaged stamps. If you abide by these rules why are some people giving low marks just because they don't like the stamps you sent. I send stamps in good faith. I'm not a mind reader & I don't know which stamps you already have. I've never given anyone less than 5 stars, even when there have been a lot of stamps that I already have. They abided by the rules so 5 stars were given.
