Now's this for a cutting-edge shopping list: bread, milk, a dozen eggs, strawberries, zucchini, orange juice, chicken, sirloin, DVD player, spaghetti, ice cream, puppy chow. Yep, buying a DVD player these days can be as uneventful as picking up a quart of milk. And with low prices like $49, it is ridiculously tempting to pop one of 'em in your cart.
