No doubt, these are all purchases I don't actually make with any regularity. But it seems to me like the prices you listed are outliers. Hershey's has cheap chocolate, mcdonalds has cheap coffee, but surely we don't take the lowest price as an example of what those things cost. If 90% of the sellers of coffee charge about $4 for a cup of coffee, can we assume that's roughly the price of coffee?
