The term that refers to an online discounted channel that is less transparent is "opaque channel." An opaque channel is characterized by a lack of clarity regarding pricing, terms, and conditions, making it difficult for consumers or businesses to fully understand the costs involved or the processes at play. This lack of transparency can lead to confusion and uncertainty, as buyers may not be able to evaluate the true value of the offers available.
In contrast, a transparent channel typically provides clear information about pricing and product details, allowing customers to make informed decisions. Open channels facilitate easy access and engagement, while visible channels describe the extent to which information is readily apparent to customers. However, these terms do not capture the essence of a channel that deliberately obscures information, as an opaque channel does.
