What is a wholesale dispensary exactly? weed-measurements-guide-info-graphic Learn about weed measurements used in Canada. Wholesale Dispensary Canada are almost entirely based out of British Columbia, home of the hugely popular “BC Bud”. A wholesale dispensary is different from “sellers” who supply many of the online dispensaries. The online “wholesale” MOM (Mail Order Marijuana) are dispensaries that sell pounds, half pounds, quarter pounds, more or less in bulk. These bulk MOMs sell their weed at reduced prices, as well as their concentrates (Shatter, Hash, HTFSE, Sauce, Resin…). The reduced prices are generally in the form of Mix & Match volume discounts, more on that later.
