They make you pay a premium for samples. Fine. I bought samples of a bottle and dropper. I only received the bottle and no dropper. I still decide to order 600+ bottles with shrink wrap. I only received the shrink wrap with no email that the bottles were out of stock. My production team can't wait any longer, after 3 weeks I call to ask for a refund. They said that it's been after 15 days and they denied me a full refund. Then Shariek, the rep, hung up on me... terrible people and unreliable supplier.
