Answer:
Selective retention.
Explanation:
Selective retention occurs when a person more easily remembers things that are closer to their beliefs, values, and Interests than things that are not.
Luis does not want to do his shopping at big box stores but prefers to shop locally. So when he reads about one of the big box stores (which is not his preference) is doing a big sale next week, he does not remember it because it is not consistent with what he wants. This is an example of selective retention.
