Need help with comic

Hello
I am looking to buy the Amazing Spider-man #168 and I have found one for $30 that has been cgc at 9.0.

Do you guys think this is a good buy?

WTF is up with your user name. It's 30 dollars, who cares.

for some reason when I made this account it connected to the school server and my school number is 110142, so it made that my username for some reason

and btw since I am only 16 without a job $30 is a lot of money to me, its not easy for me to get that much

@110142: I see, well how invested are you in your collection, and does the particular story suit you? I'd say go for it.
