Walmart offers the Presto Stainless Steel Electric Wok for $45.60. Opt for in-store pickup to drop it to $43.38. (Amazon charges the same.) That's the lowest price we could find by $9. It features a 1,500-watt heating element and automatic heat control settings.

Update: The price has dropped to $43.38 before in-cart discount, $41.16 after. Amazon has matched this price.
