We have a Walmart's Super Center south of Ensenada, BCN, and for the
past three months I have been able to buy McVitie's Original Hob Nobs,
300 grams by weight for less than 16 pesos.

The peso is just about equal to the dollar now, so that would make it
about $1.60. I can also get McVitie's Original Digestive Biscuits AND
the "light" variety for about 14 pesos ($1.40).

Seems awfully cheap for the best buscuits in the world!

When they run out, they won't reorder, though.
