PMO = Private Vendors aka Private Members Only, operate as non public Online Vendors - Not available to the Public. These companies DO have a vendor business, with some Social Media or website - But limit Sales to "Family and friends". Often due to Low Stock available. All of these PMO vendors, do sometimes open their business to New Members, usually on Social Media. Please consider - there is NO evidence that PMO means = better kratom. 😃 PMO vendors import their kratom from the SAME places - often the same Indo sources - as Public vendors do.
