Have been using their app and services for almost a year now and so far have no problem with that. Great customer service!
I am very happy with China division fulfillment service, I am a drop shipper and using their warehouse for high demand items in my store also using for Amazon FBA prep. They are working great! I don't understand why people give 1 star.
This is one of the worst applications ever don't even bother.
I sent an email to them 3 days ago but no replies until today. USELESS!
Great app! I highly recommend it to anyone trying to maximize their Shopify store!
