Vitals: Reviews, Bundles & 40+

Start to using this app two days , and found it's very helpful. Quite a lot functions in the app , and it's not expensive, it's definitely worth it. Currently we are mainly use the Upsell bundle and Pre- order functions in it. I have to say that the Upsell bundle is the most useful app i have ever use, the bundle related products recommand in the cart brings so much sell. And also they're customer service are so good, patient and enthusiastic also high skilled.
