Hello Drew,

I think your most cost-effective route is to get the Standard Level C Starter Kit $180

It has everything you need plus it is discounted because grouped together.

Another way to keep cost down more is to ask, in the comment sections of the online order form, for any books that are gently used books. If we have any in stock we will give you 20% off of each book in stock.

But note, we don't always have gently used books, it is first come first serve.

Hope that helps,
