I'm heading to the comic book store tomorrow, and going to see what Buffy ones they have, I expect they will have the newest season 12 one, so I'll get that but if they have others what do you recommend I get?
I have:
High school years: 1 and 2
Tales of the Slayer
Season 9 Volume 1
Angel and Faith: Live Through This part 1
That's a random selection of comics you got there, so my first recommendation would be, assuming you just want to jump straight into something amazing would be A&FS9 Vol. 2- Daddy Issues. As everyone else has said, that first season of A&F is amazing.
Other good places to start:
Buffy Season 8 Vol. 1- Long Way Home (this was the beginning of it all)
Angel: After The Fall Vol. 1 (this one's a little comic-booky btw)
Tales (hardcover collecting Tales of the Slayer and Tales of the Vampires)
Willow: Wonderland (if you're just a huge Willow fan)
Fray (set in the far future. S12 ties in big time)ffy
Buffy Omnibus Vol. 1 (includes The Origin [retelling of the movie script], and a couple stories that take place pre-S1)
