This nonsense on the condition cuts both ways.
A bs assistant tried to say a well-kept camera on a trade-in was the lowest grade because it had a screen scratch. It was just a tiny spot where the chemical coating had come off that didn't show with the screen turned on. The rest of the camera looked excellent. You had to wonder if the store would bump it up a grade when the trader leaves.
I won't ever buy a camera with a screen scratch. Not sure if it should be marked "Bargain" for it though. But their grading system is not nonsense and works great for buyers.
It seems that there's no wiggle room on condition when selling to them. Their business model works for them and leans heavily to the buyer. I can't imagine why I'd sell anything to them when someone within a mile of me would pay much more.
I checked them for selling my 70-200 VRII. Their offer was 875.00. I sold it in a matter of hours on Craigslist for much more without hassling, grading and shipping.
