I donated my eggs. I've made $14,000 so far, an all expense paid trip for 2 to NYC for 9 days, a 500 gift card and a tiffany's necklace.
To top it off a woman that couldn't have her own children because she had X-Rays when she was younger which killed off all her eggs was able to have a child because of me.
You have to be over 18 though.
Otherwise craigslist.
