On the streets in Manila and other parts of the Philippines, you will see a lot of people trying to earn a living in selling candy and cigarettes. You can buy them per piece. They usually cost only 1 peso or so.
Cigarettes also go per piece, around 2 pesos a piece, fire included ! 
Filipino time:
I’ve also seen a smaller version of that that they carry around in traffic.
Street vendors seem to sell virtually everything. Bottled water, fruit, newspapers and so much more.
Correct, In traffic jams lots of people try to sell all kinds of goods.
Water, sodas, car seats, banners, plants, even pots and pans.
I noticed that if a new kind of item is sold on one place, you see them within a day or two on lots of places. It looks if they all buy their stuff at the same whole seller.
