What's up with that?!
It is part of the pay for click throughs that BYC gets when someone clicks on a link here and purchases an item from a participating site.What's up with that?!
OK, Thanks @Nifty-Chicken !
So if I want to buy something from Amazon (I have several things in my cart),It's different from advertising and is an "affiliate" relationship where BYC gets a few pennies (like, literally pennies) if someone clicks and buys stuff.
