Filled a 5 gallon jug at a Neighborhood Walmart in Phoenix, Arizona. Purchased Primo refills pretty regularly up until recently. Refill stations have been nasty looking and it doesnt seem like they are being maintained and kept clean by staff or the vendor is not checking these dispensers often enough. Last jug I refilled tasted vastly worse than city tap water. Until Primo tightens up quality control on their dispensers at Walmarts I would recommend choosing another vendor or sticking with the tap out of your own home.
