I want to take a moment and clarify a few things about PDFs.
Every physical book so in this campaign comes with a PDF at no extra charge.
If you want PDFs of our previous releases, without physical books, they are available via DriveThruRPG here. The exception to this is books which have not released yet (i.e. EDZ 4&5, Carnvorous Cauldron, etc).
So, why can't you buy just a PDF for one of our add-ons?
You can, on DriveThru RPG. If we sell it to you here and then fulfill it from DriveThru, we don't get credit for the sale there (in our total sales numbers*). We sell them for the same price in both places (although sometimes there are sales there) so we decided to shift to that for this project and see how it goes.
*As an example, we've sold over a thousand copies of KINLESS in PDF, but only 75 actual sales on DTRPG count for sales numbers. If fulfillment counted, KINLESS would be a Platinum Seller, rather than Copper. It's a small thing, but Platinum Selelrs tend to attract way more eyeballs than Copper, so we're trying to get a more accurate representation of what we're selling.
But don't you want to raise as much money as possible? For the project we're funding, yes. But for the previous products we need to weigh the benefits. DriveThruRPG takes a cut on sales, but so does BackerKit, so that's not a big factor as much as generating the recurring sales where we sell the majority of our digital stuff.
