I agree with the previous posts but another option for the future - if you are in a rush for the payment,

with BUY IT NOW - specify immediate payment required - which is another option when you select the payment method.  This means that the person who is buying does not actually lock in the sale (confirm the sale) until they pay so if someone else comes along with the $$ they can buy & pay which over-rides the 1st person who still hasn't paid to confirm the purchase.  

The sale is not then done until the person has paid!

That should get you the payment quicker so long as the person does not pay via paypal echeck which can take 1-2 weeks to clear.
