I would wait till a Just Between Friends Sale. They have them 2 times a year. Go to www.justbetweenfriends.com they are all over the metroplex. I sold my breast pump there for $65 or $70. You get 70% of your money back and if you volunteer and donate items and refer people, the more you do, the more money get back from selling your things there. I would think you could get at $100 to $125 for that. There will a fall sale in August or Sept, so I would wait till then, if you can, you will get more money for it, I think. You could also try the newspaper or Fort Worth Kids magazine or maybe your Gynecologist would allow for you to put a sign up in their office or your Pediatrician? You could also try in Krogers on their bulletin boards. The breastfeeding center might buy it or maybe they would know of someother places you could try.
Hope this helps.
