I've been shopping at Exodus Provisions for 3 years now and have seen it grow immensely. They carry not only a wide selection of new materials, but also an ever-expanding selection of used curriculum. I have sold my used curriculum with no problems and received in-store credit.
The employees are very knowledgeable about current curriculum and are very helpful.
Even though this store is a 45 minute drive away for me, I make sure to visit at least twice a year.
Exodus is also online www.exodusbooks.com and will ship for a nominal charge.
