Walmart offers the Apple iPhone 6 32GB Prepaid Smartphone for Straight Talk in Gold or Grey for $99 with free shipping. (Straight Talk match this price is a buck more; it should appear on the home page but you can also search "iPhone 6 Gray 32GB".) That's tied with our mention from two weeks ago as the lowest price we've seen for an iPhone 6 in any condition. (It's the best deal now for any carrier by $41.)
