I should've paid more attention. I was plugging a site for about 2 months and stopped because I couldn't get past breaking even. Now I see why. Turns out their payments are set to "Payments for Rebills End After: (Zero) rebills" on both trials and recurring.

Shanked! I won't make that mistake again.

HotOlderMale and Tony & Cam are the two sites in my CCBill account that are set to "zero" rebills. Good thing I didn't run them for long.
