4.1 Product Prices
Product prices are listed in Vietnamese dong (VND) on the product page. Listed prices include value-added tax and exclude shipping charges and any other fees that may apply. Before the customer confirms the order, shipping charges, any additional fees and the total amount payable will be clearly displayed or communicated for the customer to review and confirm.
4.2 Price Changes
PHAM OFFICIAL may adjust prices from time to time. The price applicable to an order is the price displayed and confirmed when the order is validly received. Later price changes do not apply to confirmed orders, except where there is an obvious display error and the customer agrees to the proposed adjustment.
4.3 Promotions and Discount Codes
Promotions, discount codes and gifts are subject to the published periods, eligibility requirements, quantities and conditions. Each order qualifies for offers only under the terms of the applicable promotion. PHAM OFFICIAL may reject any offer that is misused, used fraudulently or used contrary to its published terms.
4.4 Handling Pricing Errors
If a price, discount or total is clearly incorrect due to a technical, data-entry or synchronization error, PHAM OFFICIAL will communicate the correct price and ask the customer to confirm again. The customer may proceed with or cancel the order. If the customer has already paid and chooses not to proceed, PHAM OFFICIAL will refund the amount received using an appropriate method and will not collect any additional amount without the customer's confirmation.
PHAM OFFICIAL undertakes to disclose sale prices, promotional conditions and any potential charges before the customer confirms the transaction. No hidden charges will be applied beyond those disclosed or agreed by both parties.
4.5 Service Fees
The website charges no fee to register or maintain a customer account. Customers pay only the price of the goods, delivery charges and any amounts clearly displayed or communicated before order confirmation.
