First, decide if you want the bike. The easiest way for ebay to settle this is unwind the deal.

The scratches under the graphics, are probably from poor packing. The others look by use, especially the one near the shift lever, typical brake swing around and nick.

Go through the bike the rest of the way, is the derailleur hanger straight, does it index?
Review the images and description and the follow on questions if any and think about what is equitable.

I have had 3 bikes go sour, one was from Italy, so sending it back was daunting. I got rooked. The others were tolerable enough. One was not, but I was so busy, I could not deal with it in a timely manner, I had to let it go.
