I have waited over a week on a few auctions. They wait to hear from the seller before they contact you.
Are you waiting to hear if you won the auction, because you can pretty much check that immediately upon auction close.
Just contact them. There very good with answering emails and questions. Reguardless if you lost youd know it.
lol .... My first buy off YJA was the same thing. One of the best things I bought ! Now get the other set and reunite the family !
