I don't have any Arch books available on my bookshelf, but I was just wondering if you'd heard of:
It's a wholesale book company that caters to schools, libraries, churches and homeschools. They only sell new books, but because they're wholesale, everything's really cheap! They have all the Arch Books (119 titles, I think) plus lots of other great books for kids.
Hope that helps!
