Based on the allowances, rewards, or other product restrictions set by your administrator, there may be certain products that exist within the Zestful default catalog, but not available to you. Be sure to check out your Balances and your catalog when signed in to see where you can spend your Zestful perk balance(s). This could differ from the catalog you see on the Zestful home page.
Also, if you are hoping to make a change to what is available to you, you will need to speak with your administrator. We cannot make specific catalog changes on behalf of an admin. We suggest buying them lunch before you ask :)
