Step-by-step explanation:
I'm sure the only way 2 improve economic activity is discount sales..meaning #4 is the answer.
nowadays, walmart stores basically "force ppl 2 shop there because they buy in "bulk," which means they are the lowest price.." guaranteed."
if there is an ad that beats WM's price, they give you the discount of the cheaper price..
remember, if buying in bulk, they distribute goods throughout all locations ...
