Walmart continues to offer an iPhone 5 Unlimited talk, text and data plan via Straight Talk Wireless for $45. To get this plan, you must purchase an Apple iPhone 5 16GB Smartphone in Black or White for $649, the 32GB version in Black or White for $749, or 64GB version in Black or White for $849. Opt for free Site-to-Store pickup to dodge the $2.97 shipping fee. Either way, over two years, it would mean substantial savings over regular, no-contract service. (The New York Times reported that you can save around $1,000 by switching to a pay-as-you-go plan.) Sales tax is added where applicable.
