Thanks for the question, and welcome to Apple Support Communities.
When you click the "Redeem Now" button, you will be taken to the iTunes Store and asked to sign in. Technically, you are able to sign in with any account at this time, so I do not see an issue with you passing the gift off to someone else. The new recipient will click the "Redeem Now" button, and sign in with their iTunes account.
For more information on iTunes Gifts, see the following article:
I am having the same/a similar problem right now.
Someone purchased a song for me gifted it through iTunes. We both have active and valid iTunes accounts.
I got the e-mail saying the person sent me the song with a button to "Redeem Now". There is no code of any kind and nothing else to click on in the e-mail (except the sender's e-mail address).
I click the button which takes me to the iTunes download page to download iTunes.
I already have iTunes.
After several frustrating attempts of going back to the original e-mail and clicking in every area of the message, I follow the directions and downloaded iTunes anyway. After I download and sign-in..........nothing.
Because there is no code in the original e-mail and I am directly and only allowed to download iTunes, I have not seen/received a code for the song that was purchased.
The person sent the song again (I hope they weren't double-charged) but the same things happened.
I deauthorized and reauthorized my computer. I verified that my account is valid. I read every part of both e-mails. The person has a receipt of the purchase, but I do not have the song.
THIS IS RIDICULOUS!
Please help resolve this issue TODAY.
I had a somewhat related problem. I needed the actual code from an iTunes gift card to open a new apple ID for my dad, because he didn't want to add a credit card. I sent myself a $10 gift card by email, but couldn't find the code to open the new account.
To solve this (and other problems listed above), simply open the email from Apple and right click the "Redeem Now" button. There should be an option to copy the link, which when you paste it into the search bar will look something like this:
Copy the ################, which is the 16 digit code for your gift card.
Hope this helps
If you need the code from the email, you can just right-click the redeem button, copy the URL, paste it so you can see the whole thing, and the code is there. The code is in the URL.
Have no idea what you mean by right clicking the redeem button and copying URL....does not do that on my computer....
However, switching browsers DID work for me, from the usual MSN email interface - I used an IE browser and it linked correctly.
What an annoying code bug.....seems simple enough to fix.
The answer is what jrettenmaier and Jakalope Joe said, but in my case the code # doesn't even show up in the browser link -- the apple site insists on forwarding to a generit iTunes URL. And I couldn't right-click on the Redeem Now button in the email message. Because I majored in Computer Science, I knew I could do "Vew Source" in the HTML message and find the link text that begins with "https://buy.itunes.apple.com/", and find the text after "code=" as described by those other guys. Wow, Apple, really, you had no idea this was happening to people? How about adding a simple message at the bottom of the email saying, "If the button doesn't work, go to your iTunes application, click "Redeem Now" at the bottom, and past in this code: xxxxxxxxxxx".
