When Arundel Mills opened amid much fanfare about two years ago, promoters touted it as a cousin to the Potomac Mills -- the popular off-price mall in Woodbridge, Va. But Arundel Mills just doesn't have the variety of Potomac Mills. The stores are fewer and the buys are not as plentiful. I once spent a couple of hours here in extreme frustration, with limited time and a birthday gift to buy, and in all that time, I wound up with something that was not what I would have selected had I had the time. At Potomac Mills, in that time, I would have been saddened that I did not have enough money to buy all the things I saw that I could use. Unlike Potomac Mills, which seems to appreciate the needs of the avid bargain shopper, Arundel Mills seems to be geared more toward the family outing. There are themed restaurants galore that children would enjoy. More for the family. Bargain hunters, head south to Potomac Mills.
