The seller already has the other bass listed as coming with the case. If he changes things to accommodate you, what about the guy who is interested in the other bass who also started texting him about that one? Now he's got to do something with that sale that's not going to make anyone who buys that instrument feel like they got a fair deal.
If had something listed and knew people were reading what was offered, the last thing I'd want is some bad blood because I made a change to my listing to accommodate someone else.
