Quoted from CrazyLevi:

Let's be realistic. It's an EM and the guy is probably paying $600-1000 for it. The seller is a hobbyist who probably wants this EM gone. So they have to work out a deal here that makes sense. $300 for delivery doesn't make sense.
And it's 6 stairs. Any one of us can easily navigate the bottom half of an EM with a handtruck and 6 stairs by ourselves.
If a guy calls me up and wants to hire me to move his EM game up 6 steps, yeah I'm not doing that for less than $400 even if it's local. But to facilitate a sale on a game like this I might be more flexible.
