A while ago, Jen stressed the importance of putting effort into saving on your big ticket items because that can be where you get the best return for your time invested.
Always get a couple of quotes on big ticket items. And it can be worth your while to make sure the salespeople know you're doing that.
The transmission on our car has been having problems, so we took it to the dealer, who quoted us a $5000 price to replace it. We checked with a local transmission shop and got a lower quote. I called the dealer back and told the rep I'd be picking up the car, checking on when I could do so.
Almost immediately, he called back offering $1000 off the original quote.
Essentially, we just saved $1000 today by making a few phone calls and expressing our willingness to walk away.
