Thanks for all the input, I feel a little better about my sales. It seems like a great way to get more exposure, I sent a 3 pound package and it only cost me like $5 media mail. If I had shipped it direct I bet it would have been $30 or more. I noticed theres no way to do "no returns" for international sales though.
This is what it says on the individual listing settings..
International returns
eBay International Shipping
Returns are allowed within 30 days for eBay International Shipping orders. eBay manages any returns, with no action required by you.
However in their info page it says this..
https://www.ebay.com/sellercenter/shipping/ebay-in...No return hassles or refunds
If the buyer opens a return, eBay will issue a refund at no cost to you. You keep the sale.
I highly doubt any return ebay just eats the cost and lets you keep the money...
