Some sellers think that the buyer must wait until the Paypal payment has been transferred to a Bank Account, before shipping. For sellers with "that" philosophy, the handling time is greatly affected.

Thank you for clarifying that. I don't understand how they reach that conclusion, but surely it must have a detrimental impact on their postage DSR's. Unfortunatly most buyers will rate postage time based on the carrier's (in my case Australia Post's) delivery timeframe. I post daily, yet still get the odd low DSR as an item was presumably delayed in the mail.
