If you want a large quantity, about 25 can fit in Priority flat rate box costing $18.40, Ground advantage would cost $15, and the cheapest rate would be $9.50.  The activity books are sent from Pennsylvania, so these rates apply for up to zone 4, which covers 600 miles.  If you're further, then the slowest rate, $9.50 stays the same as does the quickest, flat rate priority for $18.40.  It can seem confusing, but just add to your cart and request a new total. I'll send an invoice with your choices. 

We also have a listing of NOS Children's Coloring and Activity Books.  They'll also have the same discount applied, and can be shipped together as well.  Just add to cart for the discount, and if the shipping isn't combined, just request a new total before paying and we'll send a new invoice.
