Product placement questions

I just saw a Hanes commercial with Charlie Sheen and Michael Jordan. In the ad MJ is in an Aston Martin. It’s pretty obvious its an Aston, you can see the manufacturer’s badge on the back of the car when MJ drives off.

Question 1 is whether or not that is product placement as it is usually done in movies and tv, or is that probably MJ’s car and the director told him to just stay in it?

Question 2 concerns the show Chuck. The products in the Buy More scenes are real. Is that product placement, or did the set dressers just go out and get a bunch of stuff you see at your local Best Buy?
