I've seen scarce, but mixed reviews of Mata Grande's delivery service. We're staying at X'tan Ha for about a week so will definitely be buying groceries one way or the other. Mata Grande is certainly convenient but how are their prices? Just a quick look has cases of Belekin at $42USD each, liter of 1-barrel for $19USD, loaf of wheat bread for $3.50USD, are they in line with the stores in San Pedro? The $25USD delivery fee is negated with orders of $250USD or more which is probably doable without much waste. Thoughts, experiences?
