Looking for input and advice on what to use for a SA payment method. Not looking to use my person CC. In the past I have had luck with Vanilla Gift Cards (you can assign a zip to them), but wanting to take a dip in the pond today and that is not working. Suggestions?  

I've done the android phone thing many times.  Of course, I have an Android phone so, yea its easy. lol.  Seriously though you can get a burner or even on of those cheap android tablets.  Last time I did the tablet thing and it worked well for paying as well as browsing the site.

I also had fine luck with Vanilla cards in the past but I tried one just a bit ago and it didn't work, which was the second card I tried after a prepaid MC from Target didn't go through either.  A WalMart prepaid Visa card worked last time, but the printed terms (US Only, nothing international) are the same as the Vanilla card I got today.  I see they still have a website to register and give an address, so maybe I will try one of those, but I am also hoping someone else can provide current intel - am I correct to assume the Google Pay method is to setup a burner Android with an account linked to a prepaid card, then use the App to make the purchase through the Google Pay?  I've never used the app, only the website, but I can setup a burner phone easy enough...

I think I have the GooglePay workaround figured out, but is there any way to use a discount code using the Android App?  Seems like GooglePay requires full price, all the time.

Go to an ATM and withdraw what you need in cash. Everything else is more hassle for both of you. If she doesn't want to carry a lot of cash alone, offer to escort her to her bank's ATM where she can deposit it.  

I think the OP asked for a payment method to pay the SA membership, not ppm.

So you are logged into the website on your Android, and able to pay with Google Pay? I had the APP installed on a tablet, but the app is not the same as the website.
