Flex redemption online

We are working on flex subscriptions; selling them is one thing, redeeming them is a different headache.  I'm wondering if anyone has a successful online flex redemption program on their site today.

Do you message consumers to redeem their vouchers:

1) on your production season/performance page? This would be easiest for the small percentage of users who buy flex, but clunky for the rest of our user base.

2) on the subscription page itself? This seems really buried.

3) just behind profile? This makes the most sense, unless those flex packages are given as a gift.

Any thoughts/ideas/examples on this would be appreciated.

 

Thanks,

Patrick
