Hypothetically, if it went for 30 Grand, then Ebay and Paypal fees would have come to about $1620 bucks or so.
The fee cap on Ebay is $750 bucks, so you start to see your rates go down after your item exceeds $7500, or around $8350 if you have Top Seller discounts.
I don't have a lot of those types of items (I don't have ANY of those types of items), so I don't reap the benefits of those rewards. LOL!
