Buying EPI

Please follow these instructions to make sure you get the most recent copy of EPI.

This is very important because you want the latest version of EPI, which is the one for which the seller is Amazon, which may not be the default seller on Amazon’s website.

First, do not click on add-to-cart from the landing page (since the default seller is not always Amazon). Instead click on the text highlighed in the figure below.

Next, find Amazon in the list of sellers, as in the example below. (Note how Amazon is not at the top of the list!)

Now add EPI to your cart, and you are good to checkout!
