I’m not sure how much longer it will last for, but Affinity has all of their products on 50% off sale right now. That includes Affinity Publisher, which, you know, I wrote a few books about using for self-publishing.
Which means you could buy Affinity Publisher for $27 right now, get the ebook of one of my books on Affinity for $5, and for under $35 be able to either format a print book, design some ads, or put together a basic cover. For under $50 you could learn to do all three.
So check it out if you’re so inclined.
