Simprosys Google Shopping Feed

Some nice features to get you started. Couple of complaints, though:
1) Customer service is not readily available.
2) Annoying amount of banner ads on their dashboard and using their tools for other apps they own. If you 'x' out, they come back in 1 minute.
3) Red alerts on the dash really mean that they have new features. Has nothing to do with warnings or errors. Red alerts will not go away.
4) I cannot put in sizes into the product unless I do it on Shopify and with towels as the category, I'd prefer to leave it out on Shopify. Google recommends/requires it. No feature with their program for this.
