credit karma & equifax are both free, i have used them both.
the good part about equifax is, & tho they may not know this, if you have half a brain you can go in & edit the webpage with your credit information.
I did that shit for my ex hoe ....she had literally like a 323 credit score lol, I changed that to a 700 with a few clicks of the button for a job that she had to provide her own credit check for.
