Goosebumps Nostalgia

Not "photography" but I want to post this here for a few reasons, to show off what I've been able to find so far in decent condition and so you can help me find more, or if you have some in awesome condition you'd be willing to give me that would be cool too, seeing as my birthday is a day away  

So far I have these books:
#1 Welcome to Dead House
#2 Stay Out of the Basement
#3 Monster Blood
#5 The Curse of the Mummy's Tomb
#8 The Girl Who Cried Monster
#11 The Haunted Mask
#22 Ghost Beach
#24 Phantom of the Auditorium
#26 My Hairiest Adventure
#35 Shocker on Shock Street
#41 Bad Hare Day

I am especially looking for the other two Monster Blood books, but yes, ALL of them really. I just want to keep these mainly for the sake of having them, but I do plan on re-reading them of course.
