Aside from avoiding long check out lines, parking nightmares and irate shoppers or store employees, holiday shopping online saves energy. According to Ideal bite, e-commerce warehouses use 1/16th of the energy used to operate retail stores. Even overnight air shipping uses 40% less fuel than the average car trip to the store. You can also send gifts straight to the recipient, bypassing double-shipping. Even better, make a pact with your family and friends to give gifts not because they feel obligated but only when truly inspired to give that perfect gift. Save yourself from unwanted presents. Less is always more.
