Straight Talk Wireless offers the Apple iPhone 6 32GB 4G LTE Prepaid Smartphone for Straight Talk in Space Gray bundled with an Unlimited Nationwide Talk and 8GB Data 30-Day Plan for $244. (Choose "Full Retail Price" on the product page, then add to cart. Then choose the "30-Day Unlimited" 8GB plan during checkout to see this price.) Coupon code "ST15OFF" cuts that to $207.40. With free shipping, that's a savings of $37 and the lowest price we could find. (For further comparison, we saw the phone without the 30-day plan for $199 three weeks ago.) Deal ends July 31.
