It isn't unusual for things here to take a long time to sell, it can even take a year, I think sometimes people don't know this and lower their price to sell something faster when they don't need to, I think we have as many members looking to sell as we have buyers, that is part of it.
I think more of a reason in this case though is 532nm, there are so many cheap 532's from China or eBay or Amazon that everyone has at least one. Notice in your sigs that all of you own 532nm lasers. Unless it is one that is high power and very expensive then there will be less demand for it than other lasers.
Another problem is the sales thread, just my opinion but to me it's very confusing. In the original post you clearly state you are selling 3 lasers for $160, there is no detailed description or photos. That by itself will cause any potential buyer to move along. Then in post number 3 Pman changes things and says that 2 of the lasers must be purchased together in a separate package. He then lists 5 more lasers, this time with a good description and a photo of all 5 (this is much better) but then he posts a photo of only 3 of them turned on, that photo should have shown all 5 of them turned on. At this point the price for the 2 lasers or for the other 5 is unclear. You then have a possible buyer in post 6, then in post 7 you now change the price to $160 for all 7 lasers. Then in post 10 Pman says the price is whatever you agree to, to me that means you are open to offers. In post 11 your possible buyer seems to have been told the price is now over $300, Pman then repeats that the price is whatever you agree and in post 13 you loose the buyer because the price doubled.:wtf: In the very next post you say this is 160 :wtf: on page 2 post 18 you have now added an additional unknown laser and now say 8 lasers for 160 :wtf: Pman then says its 7 from him and one from you. At this point it seem there are no longer 2 that have to be purchased separately, also still no photos of 3 of the 8 lasers! :wtf:
I myself fully trust you and Pman and wouldn't be reluctant to buy from either of you if you had what I need, but you can't assume that about everyone, after the confusing sale thread I predict these will never sell. My suggestion is to post a clear description with a price and a photo and a second photo showing it works of each of the 8 lasers for sale. Then offer them individually or at a discount if they buy all 8 or maybe if they buy 4 of them, and if your willing to take offers then say so but don't keep saying so if the prices are non negotiable.
