As of February 2015, an OXO food scale can be purchased through the manufacturer's website or through Amazon.com. OXO offers a handful of food scale models on its website, along with other kitchen accessories, including an oven thermometer and salad spinners.
Amazon.com sells several new models of OXO food scales and also offers used ones at discounted prices through third-party vendors. Products sold directly by Amazon.com are eligible for free shipping with a minimum purchase order of $35. OXO does not offer free shipping, but its website does provide an easy way to find a local store that carries its products.
