I meant to keep better track of our grocery expenses on this last trip. Alas, that info got lost as we scrambled to assemble drifts of cuota receipts and illegible notes scrawled on napkins. But luckily Michele Kinnon is on the ball. I prefer to do my shopping at the mercado or in small tiendas, but Kinnon is right: the big supermarkets such as Soriana can be a hell of a deal, especially when you avoid the fancy cheese aisle (impossible for me, sadly). Has anyone done a cost/benefit analysis on supermercado vs. traditional mercado produce shopping?
