AT&T is offering some pretty decent incentives if you're looking to get a Galaxy S9 or S9 Plus.

Starting Friday, preorder Samsung's latest flagship phones and you'll receive bill credit worth $150 from AT&T. There is a caveat though: You'll need to bring in a new line from a competitor to get the credit, meaning existing AT&T users will miss out on this deal.
