I was hunting for a deal on the next 'Shop Nook' release last month and it felt like trying to find a secret door. The publisher's official website often has the pre-order price guarantee, which I locked in for 'The Last Pagekeeper.' Sometimes it's just a few dollars less than the big retailers, but you get the feeling you're supporting the series more directly. Author newsletters can be clutch too—I got a subscriber-only code for 15% off the merch bundle once.
A friend tipped me off that some of the biggest online bookstores run 'buy 2, get 1 free' promotions on certain fantasy series, and 'Shop Nook' titles get included surprisingly often. It requires a bit of patience and checking back, though. I found the third book that way after missing the initial launch window.
Honestly, my local indie store's online portal matched the price I found elsewhere and threw in a signed bookmark, which felt like a win on all fronts.
