Lots of choices with good prices supermarket is the 4th floor. we enjoyed shopping here. They have free boxes also in case you want to use that.

Lotte Mart is like Costco on different floors. Very little clothing to see and buy. I took a Grab from Hoi An to Lotte Mart which cost Au$20. I was very disappointed.

There is a lot of marketing for Vincom. But not for Lotte Mart, which was a better mall. Vincom is very touristy, whereas Lotte caters more to the locals. I like Lotte a lot better.
