No, there are no extra fees or hidden charges when you redeem your reward. The full amount is transferred to your balance, which you can use freely however you wish.
If you choose a gift card, physical product, or option that costs more than your balance, you can easily pay the difference with a payment card. This way, your value code never goes to waste, and you can always make full use of its value.
Your reward is completely fee-free, and you receive the full amount to spend on gift cards, donations, and more.
