A number of women across the country are selling their positive pregnancy tests on Craigslist...and there's no shortage of buyers.

Expectant moms all over the US are selling their used sticks for about $25. One  New Jersey woman writes: 'Wanna get your boyfriend to finally pop the question? This is your chance!"

And there seems to be no shortage of sellers - and most are aware their customers could be using their tests for less than honorable reasons. 'I'm pregnant and will sell you my positive pregnancy test for $20,' one woman on Manhattan's Lower East Side writes. "I don't care what you need them for."

Craigslist has also become an underground online bazaar for other fertility items, including women are selling frozen breast milk for $1 per ounce and even frozen eggs for up to $125 apiece.

As with everything else on Craigslist, it seems that the advice "buyer beware" is definitely applicable.
