Cost of renewals is reduced:

Intel has reduced the renewal prices for Intel® Software Development products.  This will make it even easier to consider renewing early and extending uninterrupted access to product support and product updates!

Buy a Pre-Expiry Date Renewal before your one year of support ends for an exceptionally low price.  A full year of product support and updates will be added on to your current product’s expiry date.  You can buy this renewal any time before your current support ends.

If you don’t get around to buying a Pre-Expiry Date Renewal and your current product’s support expires, you can still buy a Post-Expiry Date Renewal.  This is a new type of renewal.  The discount is not as good as the Pre-Expiry Date Renewal, but still substantial.  This discount is available for up to one year after your current license expires! The renewal starts on the date of purchase, not the day your product expires, and gives you one full year of support and updates.  

If you wait more than a year after your product’s expiry date, you no longer qualify for a renewal.  If you want continued support at that time, you will have to repurchase the product.
