TOS for eBay auctions -where do you set the time limit for payment?

[Grateful11]

I recently sold nearly $1000 worth of McIntosh audio equipment to a guy,
he bid at the very last second. I sent him totals on 3 pieces, 2 were able
to be boxed together. He finally contacted me after 6 days and said he
pay within 2 days, he also gave his phone #. 2 days passed and no payment.
I called the guy, very nice on the phone, claims to be one the largest
McIntosh dealers in the country. He wanted one item shipped directly to the
factory so they could service it before he resold it. This time he said he
would pay by the end of the next day, once again no payment. I filed a
Non-Paying Bidder Alert and heard absolutely nothing for 6 days a
I thought finally I'm going to get rid of this clown and relist my items and
all of a sudden he pays like 3 hours before I can close the case and give him 3
Non-Paying Biddder strikes, which I believe would have closed his account.
We shipped the items today, I fully expect to get negatives from the guy
because I think the Non-Paying Bidder thing really ticked him off. I was
just fed up with messing with this guy. I took pictures of the entire
packaging process as he had specific instructions on how to package
the MR85 Tuner, nothing was to touch the front glass period. I enclosed
the tuner in a new trash bag and luckily it had 2 aluminum bars, one
on each side that I could put "L" shaped styrofoam around and still not
touch the glass. I had to do something keep it from sliding and
banging into the control knobs and switches. It was shipped a cardboard
box rated at 500lbs. strength, double wall.

PS: They have 7 days to pay it's a eBay rule. I think I read were you will
be able file for non payment on the 4th day and close the case after the
8th day. Not sure when it takes affect.

I found the announcement:

Faster recourse for unpaid items. A streamlined process will cut the
resolution time in half. We are also working on a new automated
option that will make the process even more efficient, cut the time to
resolution to as little as 8 days and block negative feedback when a
seller opens a claim and a buyer doesn't pay. This automated option
will be tested in late September and our goal is to gradually make it
available to all sellers by the holidays.
