Walmart offers the Straight Talk Wireless Home Phone in Black for $69.88 with free shipping. (Site-to-Store pickup is also available.) That's tied with our mention from two weeks ago as the lowest total price we've seen. This device is compatible with corded and cordless phones and does not require a high-speed Internet or landline connection. Service plans are sold separately. (For $15, you can get the 30-Day Unlimited Nationwide Calling Service Plan, for example.)
Don't mind a generic one? Shopcelldeals via Amazon offers the similar Net10 Wireless Home Phone for $49.99 with free shipping.
