It is suggested that you can also try to find a local wholesale market to purchase goods in bulk, which is especially suitable for bulk purchase, because usually the more you buy, the better the discount the wholesaler will give.
If the supermarket is bigger or more powerful, I suggest that you can also try to negotiate with the brand directly and get the first-hand supply.
If you don't want to walk around, I suggest you also consider going online and looking for an e-commerce platform to purchase goods, which will save time, cost and energy.
