A die is a tool used in the manufacturing industry to create a wide variety of products and components. From a simple paper clip, to complex pieces used in the latest cutting edge technology, dies are involved in producing products we use in everyday life. Store on the other hand would be varuhus, affär, lager etc (the latter being for storing big and small equipment, groceries etc). I admit I'm not sure about the two words "die store" in relation to each other. Good luck! :-)
