Example of a 'variable option' that depends on a quantity of 
things with a single product id number regardless of the 
options selected with it.  

The token %%prodID-*%% is a wildcard, the modifier * means match 
all product ids no matter what the modifier.  If combined with 
the modifier style variable options then it will match up with
all of them when added to the cart.  

Similar to the 004_var_opt.html file.
