Mix & Match shipping issue – temp fix

I don’t know what exactly changed, whether it was this plugin or the Mix & Match add-on, but the “per item” flat shipping rate was being applied for each Mix & Match sub product and the parent product itself. Before it used to apply only to the parent product (which is what I needed). Anyway, I ended up adding a conditional to the shipping calculation code to exclude items with a “bundled_value” in $_product. I don’t think that’s a clean solution, but it fixes my issue for now.

I could not figure out a way to solve it by a Mix & Match setting, or by a setting in this plugin.
