Hi to the US.

You have to overcome two hurdles: the registration in Spain and you need to top-up (what you call refill) the SIM card. Do you want to give here an initial top-up or want to refill regularily? It's much easier and cheaper to do in Spain than from abroad.

1.) You can go to commercial vendors like http://www.simcardspain.esand buy the SIM card and top-up for a hefty premium. They will send it to you in the US. You can get their offers too through eBay.com. But they are expensive: selling a €10 SIM for $22 incl. delivery and +21% for recharges.

2.) On eBay.com you may find cheaper options like this

3.) If you know somebody in Spain (maybe a friend of your mother), you can tell him/her to get a SIM there for her, top it up and send it to you in the US. This will be cheaper too.

4.) For refills by internatl. credit/debit cards you need to employ an agency like mentioned in the comments below with 5-20% surcharge.
