These are a few of my favorite (free) things:
1. Trader Joe's Coffee - bring your own mug!
2. See's Candy - Free sample in the shop!
3. Apple's computer's and Internet (which I'm using right now)
As I leave the country in 3 days, I'm appreciating all the wonderful free goodies the USA has to offer. As I encounter other countries free items, I'll keep you posted.
