Tips and factor to consider when doing a survey:

1. Never ever compare retail prices with online prices (Lazada/Shopee). As retailer price is always expensive for various reasons (higher rental, and employee salary, and after-sale services, etc.).

2. When you buy an item, the price difference is important, but it should not be the only factor to be considered as factors such as trusted dealer/seller, after-sale services, method of delivery (risk of product handled by courier services, etc.) and so on.

3. Be cautious of item price that is suspiciously attractive. Always investigate the reason behind the attractive price tags.

4. And finally, RESEARCH, RESEARCH, and RESEARCH before buying an item. With all the con cases happened, the buyer is also part of the fault (possible due to greed, lack of knowledge, etc.).

5. And lastly, a salesman that goes the extra mile to serve the customer should also be rewarded (not necessary by tipping, a simple gesture of acknowledging and appreciation of effort is also sufficient). Remember, a salesman is also a human who at the end looking to have their stomach filled. Accept the fact that they are with the objective of getting a profit from you.
