When it comes to old PPVs, pawn shops, garages sales, and flea markets are your best friends. Also, some of the old independant video stores may sell them. There's one in my ex girlfriend's old neighbourhood that rents them or sells them, along with dusty old NES games, too. Yes, seriously.
I'm happy to see Bully Ray get recognition for his stellar work at number 4. Also pleasantly surprised to see Kazuchika Okada's name in the top ten. On the other hand, not sure what Sheamus has done to be at number 6.
