One of the most serious problems in not only Halong City but also in various tourism spots in Vietnam is related to the price of products, or the way that sellers set prices for their goods. If tourists spend time on shopping places in this city, particularly at markets where prices have no apparent range and standard, they are usually ask for higher price for actual price of the products. Often, these prices can be 1.5 times higher than actual cost, but in some places where sellers are extremely avaricious, they can be 2 or 3 times higher. Therefore, suggestion to tourists is to carefully research about average price range of products that they desire to purchase before to not to be charged by sky high price. Tourists should bargain for a better price if they think the product is overpriced. However, tourists should not bargain in supermarkets or shopping centers, where prices are already set.

Another issue that tourists should be aware of is fake products. Halong City is located in Quang Ning Province, where has border with China. Therefore, fake products from China are bought frequently by local sellers to earn more profit. Therefore, tourists are recommended to check the quality and origin of products thoroughly before purchasing, as well as shop at ensured places such as shopping mall or authorized shops.
