What he said above^^^ +
You can not offer anything for sale on LPF except in the Buy, Sell, and Trade subforum and as mentioned in that sub-forum sub heading "Buy, sell, and trade lasers and/or laser pointers. Minimum 20 laser related posts required before thread creation."
You already tried that once in violation of LPF rules and it got deleted. Posting it in the General forum here is not much better.
100mW 532nm green lasers these days are only $6.50 to $10.
You would not get much for it , if anything, on LPF for a lot of reasons.
Try using common sense and offer it on eBay -- you might get lucky.
There is a whole section on eBay selling where people sell Wicked Lasers stuff at silly high prices to people that don't know any better.
