Best Buy, Circuit City, Staples and Office Max have all the shops there. You can in most cases, consult their websites, or they must draw on their inventories, store and retrieve it later, or you can go directly to you. Staples, for example, free shipping on orders over $ 50. But since you are looking for a “large” bag, it is better to go to the shops and physically see what concerns them, they offer what you need.
