When I owned my store, it was great to get what I needed in large bulk. That way I didn't have to go to the store all the time.
Since then however- with just the two of us, although it would be nice, the fact is its just worth storing such bulky items. If I had a small child/teenager, it would be worth the 50 dollars a year for snacks and drinks etc. At this point in my life- its not.
