Just a general heads up, purchase of Samsung EPP codes may be against their terms and conditions (specifically the clauses noted below). Obviously, a number of people may have no issue at the moment, and they may not enforce these terms easily. Purchase at your own risk.
Samsung EPP terms and conditions:
Clause 2
2.4 -You acknowledge and agree that you must not:
2.4.1 -permit any other person to access your Company's section of the Site using your login information;
2.4.2 -publish in any medium (including, but not limited to, on social media) or otherwise disclose to any person who is not an Employee, any discount on, or discounted prices of, any Product(s) offered to Employees;

A brief history of Samsung:
2015 exploding washing machines burned down a string of houses
2016 exploding phones
2017 $3000 washer/dryer - a full day and 200 litres to do a single load
I don't think you should lose any sleep about violating Samsung's T&Cs.
