Businesses along the border in Nogales, Arizona are feeling the drop in the peso as are the Mexican tourists who cross to shop.
According to the Bank of Mexico, since last Friday, the dollar to peso mark hit 20 to 1.
Last year around this time 17 pesos were equal to 1 dollar.
Now, businesses in Nogales are doing their best to keep attracting customers by offering a lower exchange rate than many other vendors.
The Factory-2-U store in downtown Nogales has signs all across its windows indicating their 18 to 1 sell price because they want people walking by to consider stopping in and shopping with a bigger bang for their buck.
One Mexican tourist who says he has been crossing the border for decades, is used to exchanging his pesos for dollars while still in Mexico.
As some stores in Nogales push to attract shoppers by providing a lower currency exchange rate, he says he might keep a few extra pesos at hand in case he decides to take advantage of the deal.
