Yeah... anywhere else it's buyer beware. On CL it sure is a case of seller beware.
Yeah I had a lens returned because it had a spec of dust in it that he found while shining flashlights through it. I asked if he tried taking pictures, but that was irrelevant to him. It was obnoxious, but I gave him his money back, ate shipping and then resold it to someone else that was reasonable.Not too sure about that. Ebay is becoming a seller's nightmare of late. Had one guy message me and tell me that a lens he bought wasn't as "good" as he expected it to be due to light loss at edges and purple fringing. I referred him to the reviews, told him that the lens wasn't faulty and that it was a known characteristic. Three weks later and he decides to open a dispute. Ebay nearly always comes down on the side of the buyer and what the hell would ebay or paypal know about lens characteristics!
I've had a few of those, not to such a high percentage discount but have had my fair share. I don't budge unless it's $5 on a low price or maybe $10 if the product is of high value.I swear the favorite "tactic" of buyers is to show up and pull "I know you said $100 but I only have $60".
