Here's a quick summary:
Anything in [] is a character class - it matches one character only. [0-9]
matches any digit. [a-zA-Z] matches any letter. Syntax inside a character
class is very different from regular regex syntax. Inside a char class, type
any chars you want to match or use hyphens to create a range, or ^ at the
start of a class to match anything but.
Use parentheses and bars for alternatives - cand(y|ies) matches both candy
and candies.
Add a + for one or more matches: a+ matches one or more a's.
Add a * for zero or more matches: a* matches zero or more a's.
Add a ? for an optional bit: a? matches zero or one or a's.
a{3} matches 3 a's.
[0-9]{6,8} matches a number between 6 and 8 digits in length.
. matches anything.
^ matches start of string
$ matches end of string.
To use one of the characters above to match itself, escape it with a
preceding \ -- \. Matches a dot.
Regexes by default try to match the longest string possible - this is called
"greedy" matching.

Thanks!
Can you also point me to where I can get a list of what each symbol and char
means? Like what you did for me but all of the possible options. :-) Or even
a good tutorial or site that I can learn the whole regex from.
Thanks again,
Kevin

A regex to match that is: ^\$[0-9]\.[0-9]{2}$
Note that $ and . are special regex characters so must be "escaped". It
means this:
^ start
\$ dollar sign
[0-9] first digit
\. Decimal point
[0-9]{2} second and third digits
$ end
