I know $12 USD is a lot of money for some people, so to celebrate 1000 sales, I'm giving away 1000 copies of The Pocket Guide to Debugging (honour system: please only use the free link if you can't afford $12!)
Here’s the link, use code BUYONEGIVEONE at checkout to get a free copy https://store.wizardzines.com/products/the-pocket-guide-to-debugging-pdf
(I can't disable the billing address prompt but you can just enter a fake address like 123 Fake st, new york NY 12345, (123) 123 4567 :))
