Only a week?

Are you sure?

Usually it was 21 days for 'new' sellers (now 30 on managed payments)....as far as I know

What did you set your pay outs too with Managed payments?   (daily? weekly?) 

As far as the drop shipping part goes, I can't help as I don't do it

But make sure you state in your listings that is what you are doing or you could well end up with unhappy buyers
