I think they've played with things in the past but generally don't. You could buy something on a CC and then transfer the balance to a 0% card then pay down over time. Assuming you can get the credit. Or buy from a different store (BestBuy etc.) that will finance.
I have aske Microsoft this in the past and also proviede this as feed back on a survey a couple of years ago. I wish this is something they would provide but I don't think they will.
