Chatgpt is an online AI service at chatgpt.com that provides a conversational assistant for writing, research help, coding support and general question answering. It is a digital product rather than a shop selling physical goods, and access is provided through a web app and mobile apps.

Savings, when available, usually come from choosing a free tier instead of a paid plan, or paying monthly rather than committing to longer periods. Prices and plan features can change, so it is worth checking the current subscription options and any limited time offers shown on the site.

It is a direct service rather than a marketplace, and you use it by signing in and using the chat interface. As it is a subscription style product, there are no delivery costs, but you may need to manage renewals and cancellations through your account settings.
