He might not be answering because he's not home until after Thanksgiving.

Not that's good practice to have an auction end when you won't be home, but something buyers should be aware of at this time of year.
Anyway, 11 days isn't all that long of a time, IMO. (Unless he promised and changed for next day air shipping.) The auction even ended on a Friday, so you can usually forget Sat & Sun as shipping days; you basically have given him just 9 days (Mon to Tues) so far. If you don't get it or an answer by next Mon night, then you can start worrying.
(That's one of the "costs" of an auction ending on Friday, vs Monday or Tuesday.

)
BTW, he really should have answered your emails. But depending on the subject line and or message content, it could have been autofiltered or ignored, or lost in the middle of a lot of spam, or the cat ate his email.

That's one of the "costs" you pay by buying through ebay instead of a reputable retail store.
