Photos with ads????

Its more likely the result of a lazy seller who can't be bothered to check their ad after listing.
Many times I have found Audiogon has jumbled the order of the photos up from how I originally placed them and I have to go back in and revise and reorder them again.
Sometimes twice!!

I don't get hung up on the order of the pics just the quality and the information obtained by them.

If I am looking at a Mac piece, it is imperative that the seller have the original box.  That is the only way the equipments glass front has a decent way to get to you intact.  

Shipping carton is very important. To me it indicates the item is genuine and legitimately purchased.
