To avoid individual pricings, have tables where all things are a certain price. A simple dot or x on the bottom or label of different colors can indicate which table it came from. With permanent markers coming in so many colors now, it's an easier way to price things. Red marks... dollar table. Blue mark... 50 cent table. And so on. You can do the same thing for your 10 and 25 cent boxes. A quick dot of color to indicate what box it came from.
