Amazon has no locations either; these days merchandizes and even prescription drugs are sold/delivered through mail. Walmart has 4000+ stores in the US but cannot compete with Amazon and now introducing 2-day shipping With physical location overhead cost is too high; there can be small pharmacy/distribution centers or warehouses throughout the country but one main location is sufficient. Business Model is Important and OMHE has already adopted "sell through mail" model, to which Walmart and other pharmacies are now moving to. From 17Q2 10-Q:
OMHE PPS will keep rising as there have been solid income numbers, status is "current", uplist to OTCQB is imminent and qualified management will strengthen the business, imo!
