One of the many benefits of Tiv Pro is a 5% discount on ALL gift card redemptions. That means that you'll be able to get a $5 code for 475 points, a $10 for 950pts and so on.
Once you've signed up, the discounted redemption options will automatically appear in the Redemption tab. If you'd like to sign up for Tiv Pro to get a discounted redemption, you can do so just before you redeem.
TLDR: With Tiv Pro, you can stack and redeem points even faster!
