Walmart offers the Samsung Galaxy S7 32GB 4G LTE Prepaid Smartphone for Straight Talk bundled with a Straight Talk $35 Unlimited 30-Day Plan for $334 with free shipping. (Straight Talk charges the same. Search "G930VL" to find this deal.) That's $100 off and the lowest price we could find for the pair.
Reviewing this critical insurance policy takes a little effort, but it pays off big.
