Its called patience ffs.
Also, if you get no sales, you better have some good god damn traffic. Meaning if you're raping the PPD system, the traffic has to be (For the most part) Tier 1 (US/Canada). If you can't meet this requirement, you better be getting good sales. I repeat this statement about the sales TWICE because people can't get it lodges in their fucking orange sized brains.
Get good sales, UMB will pay you.
Get no sales but good tier 1 PPD traffic, UMB will pay you.
Get no sales and useless traffic, UMB will reconsider and slash your payout to the average tier of what the traffic pertains to.
This better be the last fucking thread I see here about this, I swear.
