It's about VND25,000 (MYR4.59) for 1 kg and for that I can have 2 large avocados.
The slightly better ones is about VND40,000 (MYR7.34) for 1 kg.
I usually select those that the outer skin is dark green in color and hard so that it gives it a few days to ripe before I enjoy it. But, if I intend to eat it immediately, I'll get those already slightly soft.
Absolutely healthy and full of vitamins
