Dollar VS Paso

Is it better to use USD or PASO in Reynosa/Nuevo Progresso?

Thanks in advance.

All prices are generally listed in pesos. If you pay with $, you'll most likely get a poor exchange rate.

Way better to use pesos. The current exchange rate is the best it has been all year!

Always exchange, you won't get more than 10 pesos for a dollar in boys town.
