The concept of suggests that as a firm produces more, the average cost of goods produced goes down. natural growth survival of the fittest cost enhancement economies of scale

I think the answer would be : Economies of scale
This concept explains that a proportionate saving of total cost from operation will be gained/occur if we increase our level of production 

hope this helps

Well, i would start out by advertising a lot. take money out of unused profit to have build boards put up and internet advertising. also, make sure your store signs are large and noticeable. make sure you have good deals and prices that the average consumer would be okay with. also, location is key. being in a high technology based city/location would be excellent for your business because it is based off of technology. hope this ! : )
