Looking for Dinosaur Books for a School Field Trip

[Blade-of-the-Moon]

Wasn't sure where to post this exactly as it's an odd request for help,  I need a source for around 100 1-2.00 dinosaur books suitable for elementary kids 1-3rd grade.  They are having a field trip here at the park and it's summer reading program so they want books for it. I'm having a hard time finding that many for that much from..well anywhere.  Open to suggestions!

I really don't think $1 - $2 is realistic, but for $3 or $4 apiece you could get a whole bunch on AbeBooks.

This is a marketplace, like eBay or the non-Amazon parts of Amazon, so it might be worth writing to individual sellers and seeing if they have a whole crate of these that they could ship to you. They might give you a bulk discount.

I can't personally vouch as I've never order from one, but if you want all of the same book you could look at bulk book sellers like this one (found via google search, again, no personal experience):

I've found some for 1.00 at places like Dollar Tree and such but they only ship as parts of sets so I buy 3 books I dont need for one dino one.   

Thanks for the recommendations, I'm checking them now.
