What does I'll Leave it run mean?

I just won an item on ebay and after messaging the seller i had a reply saying nothing but "I'll leave it run thanks", Does anybody have any idea what this means if it helps the item was an iphone, it doesn't make any sense to me please help explain what this means.

"I'll leave it run" is the phrase used by Sellers when they are asked how much will they accept to sell instantly and withdraw the item from the auction. How this applies to you puzzles me. Perhaps he's mixed the Iphone up with another item he is selling. And sent you an email intended for someone else.
You should now receive a notice from Ebay stating you have won the item and asking you to pay. Just follow the instructions to pay that Ebay give you.
