How much do things cost?

We've been surprised many times at the cost of things here in Hanoi and elsewhere. Most of the things have cost significantly less than we're used to (food, beer, transportation, movie tickets, etc), although some of the things are quite a bit more than we thought (education, chocolate chips).  

Here's a rundown of some of the expenses we've had. Just how much do things cost in Vietnam?  The current exchange rate here is 22,475 Vietnamese dong (VND) per 1 U.S. dollar (USD).  I've listed the prices below in dollars and their VND equivalents.
