I have always gotten quick and informative responses to all my questions.
I had multiple packages my last order and one became lost. I waited for a while and let them know. They were quick to respond and resent the product right away at no additional charge. It was a lag in getting my product, but it did finally get here and well worth the wait.
I dont know if its me , but it seemed when I was ordering items I was looking for in certain volume were out of stock. had to waight a while for that.
