About this place

The big box Metro supermarket has the largest selection of imported Western foods of any store in Nanjing. It’s surely the place to go if you are looking for variety or looking to buy in bulk quantities. However, the prices on most goods are not as cheap as some other stores in Nanjing. Many similar imported goods can be bought at Carrefour or Aochan for slightly cheaper and some of the more common foods can even be bought at convenience stores for cheaper.
 
Metro is supposed to be for business customers only. A Metro membership card is required to purchase anything. However, this doesn’t deter non-members from shopping here. A member swiping their card for a non-member is a common site at the cash register line ups.
