Answer:
you're receiving too small of a gain
Explanation:
Based on the information provided within the question it can be said that offering a price so low that buyers immediately accept it might mean you're receiving too small of a gain. That is because if a buyer is immediately accepting it, then it can be because they realize that it is a great deal and that they will most likely not find a better price anywhere else and immediately decide to buy it from you. Therefore you can be selling it for an increased profit margin by increasing the price.
