So, I bought two Saga RRPs from eBay and they've both come in over the last few days.
The first copy was described as "NM" and I guess it is, except there's a weird waviness to the back top left corner. A couple of minor spine dings on the back cover as well. It's probably a 9.2 to 9.4 and might press higher, so I'm keeping this one.
The second was described as "NM or better, best copy on eBay" and was, ironically, worse than the other copy. Good sized ding to the lower left corner, small color-breaking spine ticks, bend to the upper left corner. It's hard to tell if the damage happened in transit, or if it was that way before. Regardless, this one is going back to the seller.
I think the moral of this story is, the raw copies you see on eBay "may" be the dregs in terms of condition. The NM/M copies were probably cherry picked at C2E2 and are on their way to CGC as we speak.
