How many FIRST books are in a case? (logoloc ?)

http://logoloc.com/first/Product/FirstBook.html

It says the price per case, but has anyone found out how many books are in a case?

i would think 10-12. from doing the math.

My guess would be 12 because 11 would be the next whole number from 520/47.95 (with a slight discount) but 12 would make more sense as an even number and an ever bigger discount.

There are 12 in a case.

OKey dokey. Sounds good.

Thanks everyone!
