Yes, they are. It should never be your intent to deceive your customer or sell a product that doesn’t do what it claims to do. If you are satisfied being transparent with your customers and that your products and services are as good as they claim to be, there is no issue with offering upsells. An upsell should always be better than or outperform the original goods or services. Otherwise, there will be no incentive for your customer to choose the upgraded option. If your customer can afford the cost and wants the best solution, they will choose the upsold items. Otherwise, they won’t.
