Storing potatoes should not be much of an issue if you plan on using them within a few days of purchase. But if you buy in bulk, or are not planning on using them right away, the way you store potatoes can affect their edible shelf life.
To store potatoes, keep them in a dark, cool, well-ventilated place.
Keep the potatoes away from any light, as light can cause the potato to accumulate chlorophyll, causing it to turn green. The more light, the more green the potato will become, giving it a bitter flavor (and the effect can be harmful, even toxic, in large amounts).
Store the potatoes in a cool environment, as warm temperatures can cause the potatoes to sprout.
Ventilation is also key. Don't store potatoes in a sealed container. Potatoes are often sold in perforated plastic bags; these bags help to keep the potatoes humid, while still allowing for air circulation.
