The Mercado Libre saga continues. My US credit card got kicked out, so we went to OXXO and paid the 2927p, cash. There was a 9p service charge. That was on the 17th. Since then, I have been e-mailing and chatting with Mercado Libre daily, because OXXO never posted the payment, even though I was able to submit the receipt on line. Finally today they credited my Mercado Pago account with the money, and I was able to pay for the voltage regulator. In theory, it will be shipped DHL tomorrow, and we'll get it Monday or so. More as things progress.
