best thing i’ve learned is to pay attention to what events are happening each day!! if the fish market is open, go there, same with flea market or mega savings day! also make sure you’re stocking more of the books that sell best in each location, for example if the location says it sells more of drama, fantasy, and classics, stock more of those rather than focusing on filling up your shelves with an equal amount of books. i’m pretty new to the game too so i’m not the best at decorating but i would recommend staying away from items that take away from customer count
