Need advice on selling/pricing used Ping G20 hybrids

I am reselling a barely used set of 4 Ping G20 hybrid clubs for my father in law. He doesn't like the way he hits them and asked me to sell them.

They have been used fewer than 10 rounds, cost about $160 each new. I have had them on Craigslist for about a month, first listed at $500, then lowered them to $400 recently.

Besides all the Nigerian princes who have offered me far beyond my asking price, I have only had legit offers in the $200-300 range from locals who don't know golf and are only looking for cheap starter clubs that I have turned down.

I have sold plenty of stuff on Craigslist before (cars, most of my possessions once I got married) and always done so quickly, so these clubs sitting around is bugging me.

Let me know if the unofficial golf board has any advice on how to price them right or somewhere better to sell them.

The ad is linked below, Thanks.
