I would ask around to friends if you want to buy one used. Someone usually knows someone selling a Peloton. I hooked my friend up with a friend of mine that was selling one.
Honestly, they're pretty cheap on Amazon these days and Amazon is about to have their October prime days so maybe they'll go on sale again. I would suggest getting new over used since you just don't know how well the upkeep was on the used bike.
Love mine and congrats on getting the bike! You're going to love having one.

I bought a refurb at a nice discount. They deliver and set it up for you and eventually offered me the extended warranty as well.

Most refurbs are people who just tried it and returned it, so they are essentially new.
