You are purchasing a pdf document of this choral piece and a license to print one copy only. To make additional copies you must purchase an additional license. Each additional copy is $1.75 a piece. Put the total amount in the price box above that currently reads "1.75+". For example, if you are going to print 20 copies put in "35" into the box. 20($1.75) = $35.
