Wal-Mart's online site is such a convenience for city-dwellers! I turn to them for everything from household products to home decor and even food. Their delivery estimate is always on-target quality is always top-notch when it arrives. Best of all, their prices are very competitive, especially if you live in a large metropolis with inflated prices.
TIP: WalMart.com offers free shipping for orders $50 or over, save up what you need to meet the minimum and you don't even need to pay for shipping!
