I checked it out all the way to signing up for it, the fee structure varies by your "Ebay experience". It was about 3.9% plus $.39 per transaction. I am sticking with Paypal which is totally free! If anyone wants to sign up, you get a $5 bonus and I get a referral bonus also

PS- I don't want to start a conga line here, just pointing out Paypal which is another free way to earn miles. If someone wants to conga, please move over to Omni
