Depends on how stressed the points are (meaning, if they are about to expire, the renter will have them on “sale” to get rid of them). Normal, I see them between $12-$14. A good deal would be $10 and stressed, I’ve seen as little as $6, but not too often.
Also, just be aware, you may have slim pickings with availability for October. That’s during the Food and Wine Festival, and DVCer’s really like going to that!
