This is why I have been a loyal Samsung customer for so many years.
Samsung gives us financial incentives either in the form of high trade in value, freebies, extra storage/ram, etc or all of the above. Because of this, I have been able to afford Samsung devices on a more frequent basis and get newer stuff more often.
Samsung has also taken care of me in certain disputes or transactions and always given me the benefit of the doubt. I had to work for it by contacting more than one representative but eventually I have always been taken care of.
There are only a handful of companies that I can say this about. I don't have any illusions about it. It is good business for Samsung and keeps me coming back for more.
One of the things I think Samsung understands is a repeat customer is really important not to lose.
