The good: big store, good choices. 24 hours. Grocery section if you need an item or two while getting something more "drug store"y.
The bad: usually have, like, one cashier on. A dumb cashier, also usually. The line snakes all the way down, 20 people ahead of you. I tried once to buy two items at the photo section instead, where the cashier was sitting doing nothing, and she said you can't. They really need to put more people behind cash.
