Supermarkets have to sell, the general wholesale daily necessities of the store also have.
Supermarkets sell slightly better quality, and the price will be correspondingly higher.
The wholesale market may not have a brand, the quality is slightly worse, of course, the price will not be high.
If you go to the supermarket more, you can buy in the supermarket. If the price is too expensive, you can go to the wholesale market, where there are many general varieties and more options.
