Costco: for electronics

Costco is great for lots of things, but lately we've discovered how particularly good it is for electronics. I recently had to get a new laptop, and a salesguy at a local computer store actually recommended Costco over his own place, because Costco includes a 2-year warranty for all its electronics. They don't have a huge selection, but they had exactly what I was looking for, which is what matters.
We also just this week bought a new TV through Costco: again, not a huge selection, but exactly what we wanted at the right price with the warranty included.
