A lot of sellers on eBay do not have the "make offer" option selected for their listings. Let's say a seller has 10 CD's individually listed that are selling for $5 each plus shipping which they will combine, and you are interested in purchasing all 10. If a potential buyer sends a message to the seller and selects the "Make offer" option via the eBay messaging system on each listing and indicates he/she will offer $4 for each one, and the seller agrees, how would the seller change the price to $4 for each CD after you have placed all items in the cart and are at the checkout screen? When sellers indicate they combine shipping in their listing, I have clicked on something to the effect of request a total from the seller at checkout to where the seller adjusts shipping when buying multiple items. Would it be the same procedure (request a total from a seller at checkout) if a seller indicates through the eBay messaging system they will accept a lower price? Just want to make it clear this is when using the "Make Offer" option through the eBay messaging system for fixed priced listings--NOT items that already have "Make Offer" prominently displayed in their listings.
