I bought a Mac Mini yesterday at the 5th Ave Apple Store in NYC. I bought it to use in my home theater setup. I was so excited unboxing the Mini when I got home. I plugged it in, hit the power on button and nothing. Not even a peep, not a whisper. It was D.O.A. straight out of the box! It would not power on. So I tried moving it to a different power strip, still nothing. Then plugging it directly to the wall. Still dead.
I was SOOOO HEATED I ended up returning to the Apple Store at 2am to exchange it. The night time manager was really nice and I explained to him I spent $100 in cab fare from my first trip home from the Apple store, then back for the return, then having to return in a cab home again. So he manually typed in a discount number during the exchange and gave me 16% off the purchase price. He said I wish I could give you cash to cover your cab fare but this should help.
The discount came out to around $100 off. I left happy.
