Help my son get a PlayStation 4

First of all, thanks for visiting my page.  My number one goal in life is to provide all that I can for my family.  My son is a good kid, a great student, and deserves the world. Unfortunately, there are some privileges I can’t afford to provide them. The only thing my son ever asks for is a PlayStation 4 so he can play with his friends. In particular, a game called Fortnite. I feel bad asking for help, but I would do anything to see him happy. Any help would be greatly appreciated, even a $1 helps. Thank you, and god bless.
