Wait... am I reading this right?Not quite. We're trying to fix two different issues here.
The first issue was that when the PDF+module bundle was $29.99 and the module alone was $19.99 for PDF owners, people who bought the PDF on its own and then bought the module were paying a total of $8.99 more than people who bought the bundle. That wasn't what we wanted, which is why we're offering an $8.99 credit to everyone who was affected.
The second issue is that the feedback we've received ... and with which, having considered our options, we agree ... overwhelmingly indicates a preference that the discount for owning the PDF be equal to the value of the PDF rather than being arbitrarily set at $10.
The experience of producing our first three modules has given us a more accurate picture of how much these modules cost to produce, which was why we decided that we needed to raise prices in the first place. Having decided that a more sustainable price point was somewhere in the $16-20 range, our initial plan was to offer the module alone for $19.99 to PDF owners, with the module+PDF bundle going for $10 more. Now that we're basing the discount on the price of the PDF, we're setting the price of the module alone at $16 and simply adding the cost of the PDF to calculate the total price of the bundle.
This does mean that the price of the bundle is $5 higher with a PDF that sells for $18.99, but it also means that the total price of the bundle can decrease if the PDF is cheaper, and it means we can set the price for the module alone to $4 less than it is right now.
For anybody who can't get subscriptions, that essentially does mean that the price is $5 higher? There's no discount to getting the bundle anymore.
