Managed Payments Part 2

Tell me again what the advantages are of managed payments to sellers? Waiting two days for ebay to payout? They expect us to ship in 24 hours. Why can't they payout within that time? I sold something on Wednesday for 40 something. I got the email yesterday about them sending my payout. But get this, since I had 2 more sales within that time and used pending payments to pay for my shipping label, they took all the shipping money out of that 40 and left me with 13. What the actual fuck? And I'm still waiting for those payouts.
