I have affiliate software on my website to track purchases
when someone buys is it possible to have that person
go back to a speciifc "thank You" web page on my site.
I'm not sure what happens after someone buys but I need
to have a page set up so I know for sure that if
they are on that page, they did make a purchase
this way I can credit the affiliate and paytheir commission
