To compare a real number and not a string, use [if blahblah == 0]. Or
use [if blahblah =~ /0/].

If the price in your products.asc is looking like "$ 123.00" or "123.00
DM" or whatsoever, you will always get "0". Test the calculation with
perl like

$a = "$ 123.00";
$b = "10";
$c = $a * $b;
print $c; ----> 0 or empty

but

$a = "123.00";
$b = "10";
$c = $a * $b;
print $c; ----> 1230.00

Another workaround is

[set name="dummy" interpolate][item-price noformat=1][/set]
[if scratch dummy > 0]
IS GREAT!
[else]
IS NOT GREAT!
[/else]
[/if]

or

[set name="dummy" interpolate][item-price noformat][/set]
[if scratch dummy == 0]
IS ZERO!
[else]
IS NOT ZERO!
[/else]
[/if]

or

[set name="dummy" interpolate][item-price noformat][/set]
[if scratch dummy =~ /0/]
IS ZERO!
[else]
IS NOT ZERO!
[/else]
[/if]
