ebay question about selling?

Does ebay fees cost less if the selling style is fixed price?? I sold something on ebay that was 113 and the total value fee is 6.65 ? that isn't 9% and i sold something else that was an auction for 81 and the total value fee was 7.27.. that is 9% I thought ebay takes 9% ?

Final Value Fees vary for items in different categories. See:

However, eBay just announced today (March 19, 2013) that all of their fees are changing very soon, so you'll definitely want to read about this:
