Once you meet the criteria for faster payments, see the link below, you will be able to withdraw your money within 24 hours of the sale.

I send most of my items as large letters with just a stamp on, so never get confirmation of delivery.

Generally though, payment is available before I post items out.

"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
