I guess I have been wrong then ;-( Even if you bought a kit from B&H/Adorama and trying to list the lens before you got it in a day or two?
I don't consider the two scenarios to be equal. In your case, B&H and Adorama are reputable sellers. It's a pretty safe bet that the item your selling is brand new and in fine condition and will arrive when expected.
When you're buying a used item from an individual to flip, you have no real way of knowing its condition before you list it for sale. If asked questions, you cannot honestly answer them. The original seller said it was great, but do you know that for certain? No.
