So this is an inference question. On an inference question, the correct answer has to be true based on the information given. Be careful of any answer choice that makes a logical leap that you can't actually make. For example:
Fact: Tommy goes to the movies six days a week
Wrong inference: Tommy likes movies
Wrong inference: Tommy seems a lot of different movies
Wrong inference: Tommy goes to the movies on Tuesday
Correct inference: Tommy spends at least some part of one weekend day at the movies every week
In this case, we are told that stores with coupons charge more for their products, because they have to compensate for the expense of making them.
(A) This seems logical (like my "Tommy likes movies") example, but it actually isn't. Redeeming coupons could still save you money. For example, you might live in a town with only one store. Your store has coupons. Technically, you're paying more than someone in another town with a store WITHOUT coupons. But as driving there isn't actually an option for you, the act of using a coupon still saves you money, because otherwise you'd be the even MORE expensive normal price.
(B) This is just a restatement of what the passage said (See above).
(C) We are told the coupon stores need to charge more in order "to compensate for this expense without reducing profits," implying that the profits more or less even out.
(D) We have no way of knowing about OTHER expenses that get passed on to consumers.
(E) We don't know about EVERY product, only that the AVERAGE price of all products is slightly higher at the stores with coupons.
Hope that helps!

Another way you might think of A as incorrect is that it's too broad. It's possible that everyone who uses coupons doesn't just use them in RETAIL stores, but also uses them elsewhere at places where they DONT have to pay more because of the production costs associated with coupons. In that case, they could be saving money in those other places.
