I've answered my own question, but thought I'd share for anyone else: My initial question I want to set shipping cost into event7 as a currency metric either in the format:  s.events = "purchase,event7=5.00"; or in s.products  e.g.   s.products=";prod1;1;10.00,;prod2;2;12.00,;shipping;;;event7=5.00";   but am struggling to achieve this using eCommerce extension.   It either ends up appending to every product like this :   s.products=";prod1;1;10.00;event7=5.00,;prod2;2;12.00;event7=5.00,;shipping;;;event7=5.00"; (which inflates the shipping cost recorded)   or it just sets event7 as a single success event like this:   s.events = "purchase,event7"; (which doesn't record a cost value)   I've tried using JS extensions to overwrite s.products, s.events, utag_data.shipping_cost or _cship but to no avail.   Any ideas?   Do I have to use do_Plugins to achieve this?   My solution Yep.  I had to use s_doPlugins in a custom Javascript extension. Just had this code in there:    s.usePlugins = true;    function s_doPlugins(s) {    if(s.events.indexOf("purchase")>-1){       s.events+=",event7="+utag_data.shipping_cost;    }    s.plugins = ""    }    s.doPlugins = s_doPlugins;  And set the scope to Pre-Loader and SiteCatalyst and ran it after the eCommerce extension. ...
