I have another post below. The topic of this one is mostly unrelated.

Background:
I've been intending to hire a
particular window installer, though no contract has been presented yet
to sign. In addition to the windows we are ordering, he mentioned he
had a door already in hand that would be a good match for one we need to
replace. We said we were very interested assuming the condition was as
good as he stated. The door isn't even an approved part of the insurance claim
yet though it will be submitted.

So here's the question:

After confirming our interest in
the door, though still not included in the claim, he responded saying he
will have the door delivered to us in a couple days. Windows of course
have to be ordered and are a few months off. I just find this odd.
Are there any legal consequences to letting him deliver this door to
us? Does accepting it, even though it won't be installed, bind us in
any way to purchasing the door or anything else? I'm want to give him
every benefit of doubt as I do trust him, but it just seems weird. For
one, it could get damaged while it sits in our home somewhere the next
few months. Furthermore, insurance still might not approve it for our
claim. On the other hand, maybe he just wants it out of his storage as
it is a year or two old. Am I falling for something here? Maybe he
just feels like if he gets his door in the door, haha, we'll commit to
him no matter what.

If we decide we don't want the door, or if
insurance doesn't approve it after it sits in our home a couple weeks,
will we be stuck purchasing it anyway for some legal reason? There's
still a small chance we wouldn't even use him for our windows, if
there's something we really don't like about his quote. Am I being crazy? I guess I've just read about how you never let a contractor begin work without a signed contract... is delivering materials different?

Thanks everyone.
