It is important to keep track of how products are selling and how people are reacting to your marketing campaigns. If there are certain products that customers do not seem to be buying, it could be time to stop offering that product. You should also think about the profit margins of each product. If a product has a larger profit margin but is less popular, it could be worth continuing to carry that product because it brings in more money when a customer does purchase it.
