Come on, $100!!! You are torturing me Pennsylvania craiglists seller who obviously have no idea how desired an almost complete mid century walnut dining set is. The wood looks worse for wear but it's nothing some elbow grease, danish oil and Howards Feed and Wax can't fix.
This is another great mid century walnut credenza and it looks like it's in pretty decent condition (from what I can tell from these not so great photos). You should buy it.
