self-competition en · NOUN
Etymology
From self- + competition.
Meanings
-
(uncountable) Competition between retailers, products or services owned by the same brand.
However, when our product is required to compete with itself by the reckless and irresponsible commercial conduct of price cutters, our ability to compete diminishes. This self-competition among different outlets for the same branded product is morbid competition, a perverse corruption of the concept of competition itself which leads to its destruction.
