I called up with that exact question… and got the impression that eBay is going to picking up a lot of calls with the same query.
Paypal used to give sellers their money immediately
But it was effectively loaning the money because it takes two days to clear
Oh heck, we should have appreciated PayPal more
If everyone starts to hate the new managed payments system, there is a possibility that eBay will introduce its own PayPal type system, to give sellers the money on sold items upfront.
Its better for compliance as most people use PayPal for many personal and business purchases
It will be easier to show in a tax return document monies received direct to an allocated account
I don’t know what will happen about the extra 5 months you had with PayPal to chase up any disputes on orders. Which effectively meant users of eBay had 6 months insurance, in case an order went wrong.
