I use 2 different prepaid debit cards here in Mexico for paying bills / purchases online. The cards are Ualá and Albo, both are ordered via the internet and can be loaded with a sepi transfer from my Mexican bank. They work for paying services like Netflix, Cfe etc. and also online purchases from Amazon and Mercado Libre .
