Does Best Buy hook it up?
If you are replacing a gas oven with this gas oven will the delivery men disconnect the old stove and connect the new one?
Unlikely. The delivery guys are different than the install guys in most states. The delivery guys are not likely to touch your gas lines, you need to pay for install or do it yourself. That said, install is really easy if you already have a shutoff vale at the stove and you buy the correct parts to do it, search online and find the correct fittings/lines and supplies (gas grade teflon tape and leak check fluid).
