For Apple fans, today marks a big moment for the brand: an announcement about the newest version of the iPhone, for starters. While rumors have been flying for months now about a sleek update to the device, Apple has given few hints as to what it will actually debut, and just as importantly, when. That will all change shortly, as the company is set to let their fans in on the latest products and when they can buy them.

Though some product images have been leaked, no one is sure just yet what to expect of the phone. However, eBay and eBayUK are expecting a huge surge in Apple products listed on their sites, and are adjusting their policies in preparation. The U.S. site had this to say:

Listing the latest Apple products as pre-sales
Sellers in full compliance with eBay’s Presale policy will be allowed to list the latest apple products on eBay, 30 days prior to the launch date. Also:
Apple-authorized resellers may list up to 25 items per week.
eBay Top Rated sellers may list up to 4 items per week.
Sellers meeting our minimum performance standards may list 1 item per week.
Only sellers registered in the United States or Canada on eBay.com, eBay Motors, or eBay Canada, will be able to participate in this event.

Listing the latest Apple products after the launch
Once the latest Apple products are made available to the public, most sellers will be allowed to list them with some limitations:
Apple-authorized resellers may list an unlimited number of items per week.
eBay Top Rated sellers may list up to 8 items per week.
Sellers meeting our minimum performance standards may list 4 items per week.
Sellers who’ve confirmed their personal information may list 1 item per week.
Only sellers registered in the United States or Canada on eBay.com, eBay Motors, or eBay Canada will be able to participate in this event.

Also, sellers who don’t meet the minimum performance standards won’t be allowed to sell Apple products at all. eBay says these precautions are to help sellers and buyers get the most out of their deals, and, presumably, to keep chaos at a minimum.
