What you can buy for $112.50 pesos

in the Farmacia Guadalajara, on a Sunday afternoon (all prices in pesos):

1 roll of paper towels @ 7.50
1 loaf of multigrain bread @ 14.00
1 50 g. bag of pistachios @ 11.60
1 14 oz can of frijoles @ 9.70
1 package Halls lozenges, pinapple flavour @ 3.60
1 small notepad @ 11.30
2 bic roller pens @ 13.00 each
1 small package of saltine-type crackers @ 4.80
1 small package of cookies @ 9.30
1 package turkey weiners @14.70

For a rough average, I divide pesos by 10 to get dollars, but it's more like 11.
Total about $13.00 Canadian.
PS There is no sales tax here.

Some things cost about the same as Canada, most things cost less. San Miguel is expensive compared to other cities in Mexico, because the international community has pushed prices up, and stores know they can charge more. Shopping in the markets is cheaper by far, although even there, I will typically get charged more than a Mexican would for the same product.

For the very best deals, you have to go to the Tuesday market, which is huge, and scout voraciously and barter. Discuenta para dos? Discount for two?

Adios
