Just piping in here…
The support from DesignLoud is *unbelievably* good if you use their support system as they request.
I found an issue that was preventing this plugin from working the way it was supposed to if the product attributes had a space or special character in them.
I put in a support ticket on their website and received a reply within a few hours… on a Saturday no less! Derek from DesignLoud went out of his way to try to find the bug and when it was identified, was quick to turn around an update that fixed the problem.
I was frankly amazed at how much effort they put into supporting a FREE plugin. If only developers of paid software supported their packages as well as DesignLoud does this plugin!
