WoW Insider http://atu.ca/f8b4 : It's probably not helpful
to hundreds (thousands?) of customers who suffered the
slings and arrows of BlizzCon ticket purchase, but scalpers
are already selling tickets on eBay
http://atu.ca/BlizzconTickets

Blizzard's rules for BlizzCon are set up to mitigate
scalpers' ability to resale on eBay and other internet
venues. The ticket pickup rules, from the official BlizzCon
website say:

"Tickets and badges must be picked up at the Anaheim
Convention Center; Blizzard Entertainment will NOT be
mailing the badges out. To pick up your tickets, you will
need to provide the credit card used to make the purchase.
There are no exceptions to this."

And as one eBay scalper says in his auction, he'll have to
deliver the tickets "near" the convention center. So, the
buyer should beware. You don't have any assurances your
scalper will actually show up, and you could find yourself
out a grand or two pretty. Of course, you'd kind of be
bringing it on yourself anyway.
