Quoted from Allibaster:Ebay is cracking down on this. They'll look through your messages, and if any non-eBay contact info is shared, they'll say you violated the terms and charge you the final fees.
Someone on Pinside posted their experience with this not too long ago even though the pin was purchased by someone else off of eBay.
Yup I got an email from them telling me I was in violation when I had a Pro Basketball listed recently. They didn't charge me fortunately. And I was willing to complete the sale through eBay. I was surprised on how many potential buyers wanted to complete it outside the listing. The trouble with higher dollar games is most buyers also realize the fees involved and know it's in both your best interests if you can complete a sale off of Ebay.
