Placing the order for the head unit bundle was quite easy, But at the start of my choosing which head unit suited me a side window popped up saying sign up for sms notifications and I will be eligible for 10% off my order. So I signed up and waited for the discount code to be sent, and I waited , and still no code came through. So after a while I began thinking that was a waste of time and I placed the order. And then straight away the discount code came through..???? So I missed out on the discount for my purchase. Very cheesed off about that. I hope the order goes a bit better than the advertising.
