Do they take old appliences

Yes.

For $15 bucks each they will remove old washers and dryers, when they drop off the new appliances you have purchased, so this maybe the same for refrigerators and stoves and such items

Not sure

Unfortunately I don't know, I'd hate to give you bad information. I would call and ask, if I remember correctly best buy does, don't hold me to that though. Sorry, wish u could help more.

I think for a fee
