Reduced prices on some products are a benefit of IEEE membership.
In the IEEE Memberships and Subscriptions Catalog, if you are not logged in with your IEEE Account, you will be recognized as a non-member. In these cases, once you select "Proceed to Checkout," you will be prompted to sign in, and the correct pricing will present.
Prices may change depending on items in your shopping cart at time of checkout. For example, while shopping anonymously (before logging in or before joining the IEEE), you may add IEEE membership to the shopping cart. Member prices will be reflected as the system anticipates your intention to join.
When initiating the purchase of a standard, journal, or conference article from IEEE Xplore, your pricing will be that of a non-member. Once signed in, member pricing will take effect.
