At Wishlist, we want to give our users as many options as possible when it comes to redeeming their rewards. With that, we introduced the Upgrade feature, a way of providing additional options for reward redemption.
You can think of the original reward you received as a credit towards the reward you are now contributing towards.
An upgrade occurs when a reward's cost exceeds a user's reward or wallet amount, requiring them to pay the difference out of pocket. Upgrades are displayed differently depending on which marketplace your company is connected to.

When selecting a reward worth more than your Wallet Balance, during the checkout process you will be prompted to pay the difference.
Important Note: Wishlist Rewards is a US-based company and although “upgrades” (transactions made beyond your wallet balance) will display in the currency you select, transactions will be settled in USD. This means you will see an upgrade displayed on your bank statement in USD. Foreign conversion fees may apply. Inquire with your bank about foreign transaction fees.
