Walgreens & superstores in Puebla?

Not sure if Puebla is considered the southern region. Nevertheless my wife and I met a fellow the other night in Oaxaca who ways he goes to Puebla once or twice a year to stock up on all the American items he used to buy in the States. We're pretty sure he mentioned that there was a giant Walgreens there, in a center with other mega stores. He takes the bus to Puebla from Oaxaca, (2 hours we think he said), goes shopping, then turns around and comes back. We're thinking of trying it, but are trying to find out where this center is, and if it is reachable by taxi from the main bus station in Puebla. Anyone know? We'd ask that man we met, but we may never meet him again. Thanks!

No, Puebla City is not considered Southern Mexico nor, in my experience, would you find what you call "American items he used to buy in the states." there. Almost certainly you would not find "American items" at a Walgreens in Puebla City.

Tell me, first of all, what you mean by "American items" and if so defined, why in God´s name, if those are things you wish to acquire, you would move to Oaxaca City of all places. The city of Puebla is a wholesale center for goods and services supplied the relatively isolated and provincial Oaxaca City but, while Puebla City is many very nice things, it sure as hell is not a place to look for what you are defining as "American things". If you desire "American items" then that is where you shoud be.

The largest and most sophisticated urban conurbation in Mexico is Mexico City itself but, like Paris or Berlin, one is limited ordinarily to items locally in favor or in favor of existent ethnic minorities. If you want "American items", then there is only one place to go anywhere within central Mexico and that would be Lake Chapala with its large foreign colony. Puebla City is a regional town of little international consequence. If you look for good foreign food there I suggest Burger King. This is a big hick town with an unusually high and undeserved regard for itself. Other regional centers such as Morelia, Oaxaca City and the like are even worse.
