Cornerwolf

Not easy to use at all. It struggles to connect to Pages, and the shop doesn’t function properly. Sometimes the Facebook Shop works—but often it doesn’t. Product tagging is unreliable and frequently reports items as unavailable even when they’re in stock. Support is virtually nonexistent; instead of real help, you’re just pointed to generic setup instructions. Overall, it’s been a frustrating and disappointing experience.

It’s a good service and makes importing new items easier. It needs a little more work, like GTIN import.
