I was thinking about all the sponsors I sent traffic/sales to for a few hours or a few days and/or used once in awhile, got sales with and then I never sent traffic to again, and also didn't reach the minimum payouts... I probably have balances in at least 20 accounts over the past 4 years that I will never see the money from, unless I send them traffic again haha. So, some sponsors got some free sales on me!
Anybody else do this?
