“Is their a daily limit that I can purchase?”
There is not a daily purchase limit, but there is a limit in the amount per purchase. The max that you can purchase in any single transaction is 30 grams DFE (Dried Flower Equivalent). This applies whether you purchase at one of Cannabis NB's retail stores, or on cannabis-nb.com. The limit is in place to assure that you, as an individual, are able to stay within the legal limit of how much can be possessed in public.
