Hmmm....

Well, I'm not a lawyer and don't play one on TV, but I'll bet some set
of laws in one of the states involved cover "merchantability" and
"implied warranty" and some other things that they can't get out of
even under contract. By all means have a word with Husqvarna...

Aside - 20 years ago a friend wore a hat that said "Husqvarna Repair
Team" and I said "how did you get that" and he said "you buy a
Husqvarna chain saw, you are on the repair team". Right. Check.
Don't ever buy one of those.

As for the internet versus local shop debate, it's quite clear to me
that some internet shops will take returns much more liberally than my
locals will (or can afford.) There are some products that are hard to
find locally. And there are some products (cameras, notably) that
seem to be the same price at every reputable dealer, and a different
same price at every shady one.
