There are several companies that deliver Uvinum orders. It will depend on the affiliate and the country they are at, since each Uvinum affiliate ships with the shipping company they usually work with.
On some occasions, depending on the affiliate, the shipping company's name will appear just bellow the product in the shopping trolley, even though in this case it may also end up changing, since there are affiliates that work with several haulers and choose one or another depending on your order's weight and destination. Likewise, it can happen that your order's confirmation shows one or several hauler's names and finally a different company delivers the order. Moreover, if it is an international shipment, it is frequent that the local agency that delivers the package is not the same that picked up the package originally.
