Donation Options

I would like to donate but I don't really want to give a random website access to my financial information( I get it goes through a different site,but there are ways to get the information). I can't buy the MINT cards apparently since i live in the US, I have no problem going out later and buying a Subway gift card if I have to. I was wondering if I could buy a prepaid VISA and use that. I didn't want to buy one and then not be able to use it here,doubt they'd refund it and euros aren't valid here. I've run into problems trying to use a prepaid visa card or a visa gift card before and didn't want to throw my money away.

I also live in the US. I went from using my bank card to going to a Walmart
And buying a refillable visa. Worked great. At one point it stopped working. But it started working again.
So idk. Haha.

Was it a greendot visa card? After 30 minutes of buying it, paymentwall told me transaction was unable to complete.
