I can honestly say that I would not be happy with those either.
E bay sellers and ebay themselves. The beginning of the month I ordered one of the workbooks I wanted for my son for school this year. I always look at the rate and won't deal with anyone below 99% if it's something I really want or need and can't find alternatives I might go with 98.8% positive. I usually have awesome experiences. I've been using ebay for over 7 years now. Well, I learned my lesson in not going to look at the negative feedback as well, (I do every once in a while but not as a general rule....now I do.) I only do the BUY IT NOWS so I pay at purchase. A couple days after I purchased I recieve a ebay notification saying the seller cancelled my order. So I went to check it out. Reason being they were out of stock or couldn't fill the order for another reason. OK- but the listing is still up to purchase from. So I go and actually look at the negative feedback and there was something like 90 something negative feedback for the last month alone and most of them were complaining about the seller cancelling the order and the item still being listed as available. (Now, it's my bad that I didn't take the time to look at the negative feedback as well as the positive rating, I wasn't happy with myself.) BUT why is this person still being allowed to sell on ebay? And on top of that, it will not let me leave feedback. (I don't understand how others could after they were cancelled, but I am unable, but it wouldn't give me the option to leave feedback.)
Here's the kicker, I started looking at the negative feedback on some like items and found the same thing. One seller had nearly 200 negative feedback for the last 30 days. They might have had 3000 positive feedbacks for that time, but if you have 200 negative reports and many saying the same thing, there's a problem. I understand as a buyer, I should be looking at the feedback better, and I am now, but that is ridiculous. Especially considering not all of us apparently are able to leave feedback.
