I'm Thinking of purchasing a Shurvend to increase vending revenue. I currently have 15 drop shelf machines, 7 of which are in front of my building, 4 in back of building, and 4 under my drying shed. Kind of all spread out. If i get a stand alone glass front. Should i put it in the front of my building and sell my drop shelves? or put the the drop shelves in the back of the building near the drying shed and have 2 centrally located areas for vending? Any suggestions would be appreciated.
