Less Is More: Salad Dressing
The golden rule of buying in bulk is computing the cost per unit (just make sure you know what you're comparing
). And when it comes to salad dressing, mayonnaise and other condiments, doing a calculation is smart, but there's more to consider. Morgan has calculated the price per ounce on salad dressings at warehouse clubs and supermarkets, and found that if the supermarket is having a sale, she can actually get it for less (and don't fear generic brands: Some chefs actually prefer them
). Even more important, though, is that it can be near impossible to finish that gallon jug of Caesar salad dressing before its expiration date passes.
