Here is my story of how LuckyVitamin is almost like a scammer, from which many people have shared many similar or bad experiences of buying products and should stay away. I have two orders that are under delivery process, but there are a couple of products that have been AUTOMATICALLY canceled due to the shortage AFTER I placed the orders, and the packages got shipped out WITHOUT ANY FURTHER CONFIRMATION WITH ME. Their customer representative just disappeared and didn’t seem to respond to my emails when I was asking for full cancelation of my orders or waiting for all the products I placed available back in stock. Even though they only charged me for the products that got shipped out, still, this is not the way of offering a sales service that forces consumers to accept the deal that has been changed without their awareness. Now the packages are on the way to my country, and I can only choose to take them without a couple of products I originally placed in the orders OR leave them to get them shipped back to their warehouse but without any refunds back. Besides that, their shipment is EXTREMELY slow that for sure will drive you nuts, which, according to comments from others, even sometimes gets your packages lost and never finishes the delivery, and of course, no refunds back. Also, they will close the window of canceling an order in a very short time after you placed it and take a very long time to ship the package out. I had a wonderful experience with iHerb, but it is currently not available for me because they have some issues with the custom in my country. Otherwise, LuckyVitamin has no way to compare to and compete with iHerb in my experiences, and I will NEVER EVER suggest their service to anyone. Finally, LuckyVitamin, Yu-Chieh here, if you are reading this post, please reach out to me to continue our previous conversations about the full cancelation of the orders and the refunds.
