Day 27: Buy in bulk...or not
US consumers love to shop in bulk. Buying in bulk is great: it saves time and eliminates the need for multiple store trips, can often result in lower price per unit, and can use less packaging.
Unfortunately, it also can lead to a lot of waste. While you will eventually use the 36-roll pack of toilet paper from Costco, you may or may not use up that 8-gallon drum of mayo before it goes bad. In the end, buying more than you need costs you and the environment.
