As of February 2015, microwave/convection ovens can be purchased on the websites of major online retailers that sell small appliances, including Amazon.com, Walmart.com and BestBuy.com. A wide variety of brands and designs are available across these websites, including some refurbished models.
Some of the top brands of microwave/convection ovens for sale are Samsung, Cuisinart, Sharp and Frigidaire. These appliances range from $89 to $608 on Walmart.com, and BestBuy.com carries some full-size oven combos that cost as much as $3,670.
Free shipping is available on some appliances from all three of these retailers, but terms and conditions apply. Amazon.com requires a minimum purchase of $35, and items sold by third-party vendors typically do not qualify.
