I know for Walmart $20k means nothing, but for me the affiliate commission I get on those 20k does. I get around 4% ($759 this month), which is actually pretty low for an affiliate program. But the conversion rates are pretty high.
24% of my visitors on Waltrack click on a link to Walmart and there
13% of those actually buy something on Walmart.
Now it's just a matter of getting more traffic and hopefully, July will be the first $1k month for Waltrack!
