To redeem an Opus+PayPal gift card all you have to do is check out from ShopOpus.com with PayPal as usual. Once you have logged in to your PayPal account, but before you are prompted for personal payment information, they will ask you if you have a PayPal gift card that you would like to 'redeem'. The word 'redeem' is a clear link. The following page will ask you to enter the gift card code. So, just enter your gift card's code and you're all good to go. Thanks!
