If your account has a subscription that is expiring within the next 90 days, a Request Renewal Quote button will appear on the top of your resource page. 
By clicking the Request Renewal Quote, a popup will open that will allow you to start your renewal process by emailing your sales representative with your request.
You can select to have a sales rep email you a price quote for the subscriptions you select, or you can select for a representative to call you.
Note: This action will email your sales representative to send you a price quote, it does actually trigger the subscription renewal process to begin.
