Yes, I have IPR turned off and Buy It Now listings dont require immediate payment, allowing me to combine shipping for buyers.

However second chance offers being sent out require immediate payment if they are accepted. 

Doing some research it seems that this is an ebay rule now and there is no way around it. Some have suggested turning on local pickup option and this will allow them to BIN but not have to make immediate payment. Not sure if it will work but I shall try it.
