LA Times on peso

In urban centers in Mexico the loss of purchasing power is happening. Zihuatanejo is a true Mexican economy for the most part.
It is quite noticeable what is happening in northern Mexico.

Any price increases are from the increase in petroleum products and energy costs. Unlike in much of the world where prices have fallen, our fuel and energy monopolies have only risen their prices over the years. Lots of folks are complaining about their last electric bill. And gasoline and cooking gas cost more than ever. There's no reason to raise prices because of the exchange rate except on imported items. There's not much we import from the USA because they don't hardly make anything there anymore. Everything nowadays comes mostly from China.

It's a shame to hear Baja imports so much from the USA. Gotta make all those gringos feel at home!

Places like La Comercial and other large Mexican department stores try to purchase locally whenever possible. Now if you're going to suck down foreign booze, then yeah, you'll probably pay more for it.
