Greetings friend @juanmolina

Certainly at the border, the use of foreign currencies such as the Dollar and the Colombian Peso, mark the dominance in the exchanges of purchase and sale of basic products, useful appliances in the homes, and agricultural inputs, this last element is the most disadvantageous, because it increases the price of vegetable and animal raw materials. I live in Santa Bárbara de Zulia, only 2 hours from Norte de Santander - Colombia, and I certify that in this region the Bolivar as a circulating currency has practically disappeared.
