Good stuff, craz. Did you ever try ACH-pull?
So we have...
ACH $0 unless it fails --> then you risk a fee from the "puller"
credit $1
debit $2
...and we can rule out credit (use regular CC -- earn points, instead)
So ACH creates a NSF fee risk! Can we expand on this, please. If you've tried ACH and you're posting here, please list your stats.
Me: 1/1 ACH success rate
