Spontaneous shopping

A partial list of things you can buy on the bus for 1-2 bucks:
1. A miniature tool kit.
2. scissors.
3. A very nice pen.
4. A little wallet.
5. A straw bell-shaped hat.
6. A lovely fan.
7. A performance from a crazed clown.
8. Ice cream.
9. A "miracle" foot cream
(It should be noted that the above list is just the meager remains, I've heard, of what you could get on the bus before the shiny new, super problematic Transantiago bus system was introduced)
