Not the same the same this at all actually.
Resellers buy from retail/discount and resell new or old things for a mark-up that the market bears.
Stockists are official third party sellers that have to comply to the brand's stipulations, sign contracts to that effect and sell at the recommended retail price that the brand sets.
My apologies, I work in retail and we call our concessions (non company stores) resellers . All good
