There are 2 types of stacking.

One where a merchant has a longer term advance/loan and doesn't qualify for a renewal but needs a quick shot of cash for a specific purpose. And they can afford it.

The second is the banged up cash flow biz who really can't afford it takes a stack. Has a hard time after a month or 2 and takes another stack to keep the boat floating. Then has the same problem again and gets a 3rd. If they still manage to keep enough positive balances they may even take a 4th. Then it all goes to hell.

Which one is more prevalent? There's a clear winner from what I see day in day out.
