Hi all!

Just need a wee bit of advice here... Keep in mind I am 66 and, despite being, formerly, an electronics technician (servicing two way radios and stereos of a type you all would probably call "vintage"), many of the new digital devices and their associated services and software have sort of left me behind in the dust as far as understanding goes.
Okay, on POF.com (plenty of fish) (I know, I know, I shouldn't be messing with those crazy things) I met a woman seemingly interested in a transgender woman or any other woman for long term. She is CLEARLY aware of the following:
I am a non-op transgender woman, I am retired (therefore must be assumed on limited income (and I am)), and do various fun, odd jobs for a little extra money (general and medical transcription a few hours a week, providing safe rides for LGBT folks (kind of like Uber or Lyft but I am not associated with them) that happens a couple times a week, and delivery for a restaurant.
She and I traded pictures, asked about this and that, she wanted to make sure I was serious, etc, etc. She is a Nurse, currently working in Yemen helping with injured soldiers under United Nations. Our communications have been going on a week as of the date of this post. She is low-key, not loud or braggy. Seems very much enthralled with me.
Then, she asks me to, like, and I quote: "Honey can you get iTunes card for me"...
First, I do NOT know what in h--- an iTune card is. (I guess I'm showing my age here!) That is one of those digital thingies that I just never got involved with. She has related to me how lonely she is on that base in Yemen quartered in a ware-house-like building with Spartan facilities. She is on duty 7 days a week and sleeps basically alone. She has another 5 weeks then will return to USA. She is 42. I listed myself as 56 because I look even younger than that. As soon as one starts chatting with me I reveal my age. They usually don't believe it. My profile CLEARLY states that I am a no-op transgender woman. So anyone contacting me knows that off the bat.
Anyway, so continuing with the iTune mystery... So she wants me to get an iTune card for her, scratch it to reveal the number (huh?), take a picture of it (understandable) and send the picture via the cellular phone so she can use the number to acquire music (huh? Ooookayyy...) She suggested as what I could afford but a 100-dollar iTune card preferred (I guess that means more music?)
Anyway, the thing is, is it just because I come from a long time ago, but I personally would never, ever ask someone I known for only a week to get me a 100-dollar... ANY thing. Unless it was dire and I was starving maybe, but not for music.
Personally, I get music from the Internet, particularly Youtube. Using a video editor, I can record the screen and get audio and video. Then I use a converter to derive the audio only into MP3 and on it goes to my various devices (MP3 player and older style cellular phone). Long ago, I set up direct to tape-recorder console to record off of victrolas (record players) FM radios, cartridge players and so on. I have tons of free music, both from long ago and present.
Communication to Yemen is lousy. We cannot voice call. Texts often take several seconds to minutes to transfer. She works hard everyday taking care of wounded soldiers from various countries. She lives under Spartan conditions in what sounds like to me a Military Advance Surgical Hospital (MASH) unit.
I don't know. Maybe folks do things different these days... Hmm, 42 years old, 66 years old, actually only 24 years difference... did things change that much in 20 years?
Anyway, I am mostly just playing around but it WOULD BE nice to have a close cis-gender woman "buddy". I'll have to watch this one closely and... LISTEN TO YOU ALL'S ADVICE!
