"We’ve made it even easier for you to get your hands on some huge wireless savings. Simply renew with a 6 or 12-month plan and you’ll get $15 off. The discount will be applied automatically, so you’ll have that instant savings gratification. But you better hurry because your current plan expires in just 15 days – so you should grab this offer right now."
