let me tell you, it's like a treasure hunt with a dash of strategy. The best places I've found are indie bookstores that host author events—Brittany sometimes pops up there for signings. I snagged my signed copy of 'Eat, Drink, and Be Vegan' at a tiny shop in Portland after stalking their event calendar for months. Online, her publisher's website occasionally drops signed editions, but they sell out faster than concert tickets. BookCon or Comic-Con are goldmines if you're willing to brave the crowds; she's done signings there before.
Another sneaky tip: follow her on social media. Authors often announce surprise signed stock drops or virtual signing events. I missed one last year because I wasn't paying attention to her Instagram stories—devastating. For out-of-print titles, check eBay or AbeBooks, but brace yourself for markup. Some sellers clearly don’t know the struggle of a true fan. Oh, and if you’re into audiobooks, Libro.fm sometimes offers signed copies bundled with digital versions. It’s not the same as holding a physical book, but it’s something.
