If the marks are small, but visible when using it, see if they will give you an additional % off of the price. If they aren't visible when in use, I personally wouldn't worry about it too much and consider it a great deal for $385.
On another note: the bag is beautiful, no doubt, but my sister has the small version and complains all the time about the buckle clip. I guess it is not that easy to manuever quickly or for everyday use. She leaves her's un-done all the time and it drives me crazy when I see that, becuase the flap kindof "hangs" open. I always have to clip it closed for her!
You may want to test it out before you purchase it, and see if you think the clip will bother you.
Good luck!
