I've made attempts to purchase from them in the past without success. The problem is that they use the Latin American version of PayPal called Mercado Pago. The system allows you to put in your credit card information but then requires your Argentine ID number to verify your identity. There's no provision for paying with a credit card from the United States. If you do contact them and see if perhaps they come up with a new way to pay for their items from the United States.
