For those of you who like tenchi, anyone remember 
a certain individual who for about 5 months 
bought up just about everything involving Ayeka 
for incredibly insane prices?  All I could settle 
on was an Ayeka fetish and very, VERY deep 
pockets.  When he bid on one of my fanart items, 
I checked his bidding record (over 60 different 
positive feedbacks, all items still in databases 
sold for considerable amounts) and a very odd 
thing, that every single item he bid on he was 
the high bidder.  Kind of like this, but not as 
many positive feedbacks...

I dunno... I got paid (though my drawing wasn't 
NEARLY worth over $200, which is why I ended the 
auction before things got too weird)  

But... seriously... I don't understand some ebay 
bidders!  that's just wacked out!  So all I can 
say is... you can always get a refund if they 
don't pay, and if they suddenly start getting 
negative feedbacks from sellers whose auctions 
ended before you, you can cancel their bid.

Good luck!
