I shop at ebay all the time for everything from clothes for my kids (used), to Christmas gifts, to electronics, to hobby related stuff. I have also sold many things over the years. I have only rarely had any trouble. Mostly they were just honest mistakes that I could understand. I only once had a non-paying bidder and eBay refunded my seller's fees and I relisted and finally sold the item. I love eBay because I can generally find anything I want. It is especially helpful when I am looking for things that are not available in the stores anymore.
