Membership to the GoDaddy Pro program is free.  
GoDaddy Pro Benefits gives members a 30% Discount that can be applied at checkout towards new, qualifying product purchases. GoDaddy Pro Benefits also gives exclusive member Rewards for every new, qualifying product purchase made through Shared Shopping Cart. Depending on your tier (GoDaddy Pro or GoDaddy Pro Plus), you’ll receive either a 5% or 10% Reward to be used on future, qualifying purchases for yourself or your client if purchased through Shared Shopping Cart. Exclusions may apply to both the 30% Discount and Rewards**.
The GoDaddy Pro program has two tiers, including a GoDaddy Pro Plus tier for those who spend $500.00 or more annually. The GoDaddy Pro Plus tier receives a 10% Reward a (rather than 5%) on new, qualifying product purchases, as well as a business listing in Connect, GoDaddy’s directory of web developers and designers.
The GoDaddy Pro Benefit structure is subject to modification, cancellation, or limitation at GoDaddy's discretion, with or without notice. Redemption restrictions may be imposed to Rewards at any time.
