A couple of notes:

Almost any place you want to check for numeric equivalency
be sure to use 2 equal signs like ==

The tag if-item-data or if-item-field or if-XXX-field etc will only check
that there is a  "non-empty, non-zero " and  0.00 will be counted as a
true value because of the decimal point.

for example:

[loop
lr=1
list="
1       0
2       0.00
3       1.13
4       abcdef
5       "]

         [loop-code]:
         [if-loop-pos 1]
                 non zero, non blank: [loop-pos 1]
         [else]
                 zero or blank: [loop-pos 1]
         [/else]
         [/if-loop-pos]

         <br>

[/loop]

would produce:

1: zero or blank: 0
2: non zero, non blank 0.00
3: non zero, non blank 1.13
4: non zero, non blank abcdef
5: zero or blank:

So you need to do it differently maybe like:

[loop
lr=1
list="
1       0
2       0.00
3       1.13
4       abcdef
5       "]

         [loop-code]:
         [if term="[loop-pos 1]" op="==" compare="0"]
                 <b>this is numerically a zero</b> [loop-pos 1]
         [else]
                 not a zero [loop-pos 1]
         [/else]
         [/if]
         <br>

[/loop]


Which would produce:

1: this is numerically a zero 0
2: this is numerically a zero 0.00
3: not a zero 1.13
4: this is numerically a zero abcdef
5: this is numerically a zero



So the end result is you need to use the following to check for a zero in 
the price field:

[if term="[item-price]" op="==" compare="0"]
         This price is zero (or other text)
[else]
         Price :[item-price]
[/else]
[/if]

OR if you don't need the else you could just do:

[if term="[item-price]" op=">" compare="0"]Price :[item-price][/if]

And nothing would display if price is zero (or negative :-)


Enjoy,
