I just found two 12-bottle cases of Topo Chico mineral water for $4.99 a case. I love this stuff, and it's usually really hard to find around here.
I know that, on the face of it, importing water from Mexico sounds like the world's worst idea--visions of Montezuma's Revenge and all. But it's actually a very nice mineral-y tasting carbonated water, and it feels so wonderful to drink out of a glass bottle just like in the olden days! Ah, life's little pleasures.
