Neal Was Considering the Use of Coupons for Canned Vegetables

Neal was considering the use of coupons for canned vegetables at his corner grocery. He knows coupons can encourage customers to try his store, or even help them to purchase additional items as they shop, but he is concerned about:

A) price-sensitive customers avoiding his store
B) decreasing visits from loyal customers
C) customers forgetting to mail in the proof-of-purchase to the manufacturers
D) variable pricing
E) the promotion stealing sales of canned vegetables in the future
