Granted, I'll take my chances here on Astromart over any other astro site's classified section. The people here are great and I've never once had a deal go sour. So there's that.
Now as far as I know, that other Astro site has no prohibition against listing an item on multiple sites---but Astromart does. A rule is a rule--and this one protects those of us who use the Amart classifieds from having to compete for buyers who will never see our ad.
I've contacted two of the sellers by PM and asked them to remove one of the ads, reminding them it is a violation of the TOS. The only response I've gotten was for one to relist his item at a lower price. :S
Ahhh. Thanks for letting me vent.
