Sometimes, an item is NOT on Amazon and I don't get a percentage and it's still linked on this site. After all, I'm not a COMPLETE mercenary bastard LOL

Thank you for visiting

When you make your purchases via these links you are supporting the work of Dr. Erik Johnson. A small percentage of your purchase(s) is returned to Dr. Johnson sort of like a Discover card. It doesn't come out of YOUR purchase price. You won't pay a cent more. Amazon kicks the pennies back as a finder's fee for lead-generation. But it adds up and it's very appreciated. So, thank you.

But it works another way. Almost nothing you find on the site is untested. Basically I've bought everything I recommend here. From Amazon. And so you'll see my review on Amazon, verification that I did purchase it there, and then the link to the item. And when someone needs my help and I refer for say, Mardel Clout, the link will be to my Affiliate link. So it's mutually beneficial.
