Vietnam - Purchasing and package forwarding assistance for a food item

I would like to purchase a food item from an online food store in Vietnam for it to be forwarded to me to an international location. The website and store uses Vietnamese language and I require some assistance for purchasing, and contacting the store if necessary, regarding the food item. The food item is in a foil pouch and is of around 1 kg in weight. I will provide the link to the food item for the online store for the purchase. Since they ship within Vietnam, I require assistance in then forwarding the food item to me to an international address using EMS or couriers such as DHL for the package. I will provide payment through the platform beforehand for the purchase of the item at the online store and then the shipping cost for when the package is forwarded.
