Traditional markets (Chợ) are not just places to shop; they are places to build relationships. They offer a completely different experience from supermarkets.
1. Relationships First
Market sellers will address you as a family member. Respond with a smile and "Chào chị" (Hello, older sister). A simple greeting can often change the price or the quality of service you receive.
2. The "Walk Away" Tactic
The most powerful tool to avoid "tourist prices" is the ability to walk away. If a price feels unfair, smile politely, say "Không, cảm ơn" (No, thank you), and start walking. If they were overcharging, they will almost always call you back with a better offer.
3. Market Measurements
Produce is sold by the kilogram (Một ký). For 500g, say Nửa ký. Always double-check your change and the number of zeros on your bills before handing them over.
