Maybe it's location-based, or different where you sell the item? A quick check I see 10% and 2.9%, respectively. But there's so many variables involved, such as the length of your listing, whether you list it on one of their special "no fee days", etc.
Back in the day (years ago) I sold tons of electronics on ebay and had a rating well into the hundreds. I never felt the fees were too onerous. It's "the cost of doing business" same as if you had to pay taxes selling in a retail store, or pay for gas to drive to meet someone for an item sold on Craigslist or the local want ads, etc. Somewhere along the way you're always going to have to pay something extra. At least ebay/PayPal are pretty up-front with what they charge. IMHO OP needs to suck it up and stop whining and complaining. :laughing:
