Defining how you want it presented (like in your print statement there) is 
what ZPTs are for.  So, yes, use ZPTs for that.

Say you have a script that returns the value of resRebatePrice, called 
getResRebatePrice.... to present this information in a ZPT-ish way, you could 
write this in the ZPT:

<div tal:replace="string:Quantity Special: Each box is only 
${here/getResRebatePrice} a box!"> your formatted string will replace this 
text </div>

Or, you could do:

<p>Quantity Special: Each box is only <div 
tal:replace="here/getResRebatePrice">price goes here</div> a box!</p>
