ebay purchases have been hit or miss for me. One posted, four others haven't. Be careful on the submitting them to customer service. I had a huge purchase on ebay (9,000 dollars) and Mypoints refused to honor, froze my account for over a month and then told me that I was not allowed to use ebay through them. Pretty lame. I cashed out all my points and am now using AAdvantage Eshopping.
