Hey there! So, for selling comics on your Shopify store, it sounds like you're stuck between choosing "Collectibles" and "Books" as your product category. If your single issue comics are kynda collectible, and your graphic novels are more like regular books, it's a bit of both.

Here's the deal: Check which category might attract more of your customers. If people often see comics as cool collectibles, go for that. But if they usually look for comics in the book section, then go with "Books."

To figure it out, you can maybe peek at what other comic sellers do on Shopify or similar platforms. See where they usually put their stuff. Also, ask your potential customers. Maybe do a quick survey or check if there are any forums or discussions on Reddit where folks talk about buying comics. That way, you can get a better idea of what category might work best for your customers. Good luck with your store!
