Ebay shipping is too cheap?

Im shipping a 12lb parcel (PS3 @ 12x19x6 inches) to Colorado Springs from So. Cal . Im using the ebay shipping service and Im getting quotes that are ridiculous nowadays...like FedEx home for $17? UPS ground for $14? This is amazing....am I doing something wrong? Dang, start shipping auto parts with these guys! Make a private listing, send the buyer the link, eat the ebay fees and make up on shipping! Buyer will still be ahead!
