What do you do about a purse that looks super cute and is fairly cheap but might not fit all your stuff?

the purse is about 13 x 10 x 4, but is super super cute and is about $50 with shipping all together or $62 if in the other color, what do you think?? Should I still get it?? It might fit my notebooks and other small essentials, but im not sure about my folders. I dont need a binder and I usually bring a separate bag with me to hold my textbooks so i could probably put my folders there, but what do you think?
