Last year, I found out that if I filled out some paperwork and showed it at customs, I could have gotten a refund for the IVA tax paid on my purchases. I didn't do it, but this time around, I would like to. Does anyone have any recommendations? (for example, should I pay with a credit card vs. cash? Can I do it for all purchases I take home or only things purchased at Corte Ingles?) Is this taken care of at customs at the airport? It seems like using a credit card for these purchases and having the IVA tax refunded on the credit card is better for me, since I can't use the euros at home, unless I save them for the next trip. Thanks for any help on this.
