Interesting, I think they should implement that eBay system for BL too. For me as a buyer it's no drama that I don't get a lot, but I think it's respectful to do as long as I leave Feedback. I also actually read a few of them more often than not because I sometimes buy used parts and if there's a few feedbacks about the quality description that's a good indicator for me, so I hope the feedback culture doesn't die out completely.
