Buyer’s remorse? Never! Register for free with Benevolink.com, a website that makes shopping a charitable act, then fill your cart online at any of its more than 200 member retailers, including Neiman Marcus, Home Depot, and Sur La Table. A portion of your spending will be set aside in a special account, and every three months you can direct that money to the participating charities of your choice. Coveting some strappy gold sandals? Go ahead and splurge. It’s the generous thing to do.
