Stretch Your Two Dollar Note

In Singapore, the smallest denomination for a note is the two dollar bill. In a society where inflation is rising, what can your two dollar note buy?

I went to a supermarket and found that a two dollar note can buy the following food related items:

1) a bag of 3 to 5 small apples or oranges,
2) a pack of 5 packet instant noodles,
3) a box of 10 small eggs,
4) a loaf of plain white bread,
5) 3 cans of soft-drinks,
6) a big packet of tit-bits,
7) 1-2 packs of some leafy vegetables,
8) a can of canned food such as tuna,
9) a 1.5 litre bottle of soft drink,
10)a breakfast with a cup of coffee/tea plus a simple burger at a fast-food restaurant during weekdays, and some others.

My Comments:
This two dollar note can only buy us little food now. Imagine five to ten years later, probably a five dollar note will be needed to buy the same type or amount of food.
