We have created student and teacher versions of Evaluations because we realized that it was confusing to have an "EvalPack" (which is basically a printed student version of Evals), and an "Evaluations" product (digital only, student PLUS teacher), and no digital student-only version or way to buy just the teacher's answer key (either digital or print). 

We tried to fix that and give customers more options by creating student versions (either digital or print) and teacher versions (either digital or print), so that folks COULD buy digital teacher or digital student, and wouldn't HAVE to buy a student copy in order to get a teacher copy.  These changes are especially important as we have several new schools and many new co-op groups starting to use Tapestry, so it is helpful for both families and group leaders to be able to purchase student-only resources, or teacher-only resources.

While we were creating these new products, naturally we had to decide on new prices for them as well. To be honest, all of the Evaluations products were due for a price increase, but I wanted to change as little as possible, so we mostly kept the prices the same or lower (especially if you want to buy only a product that was previously bundled with others). Thus, several of the products are now much less expensive ($10 for a level of student-only print, instead of $20, and a teacher-only version now available for $10 rather than automatically bundled with the student digital version, whether you wanted it or not, for $20). If you purchase a printed student version and a teacher version (either digital or print), the cost is still $20 as before.

The only increase was in the digital student version, up from $10 to $15, which reflects the fact that digital products can be printed for multiple students. This does result in a modest $10 increase (from $70 to $80) for those who are purchasing all-digital for student and teacher for all four levels.

Hopefully this explanation is helpful!  Please don't hesitate to contact Customer Service if you have more questions. :-)
