Did you notice that there is no promise of a money-back guarantee anywhere on the product description page? It's for a reason:

Some products are non-refundable, and the Paint Color Cheat Sheets is one of them. Because of the fact that it's an instantly downloadable ebook that can be easily copied, all sales are final.

By purchasing the ebook, you agree to these terms, so please read the product description carefully to fully understand what you are getting before placing your order.
