Modgirl, some sellers do take returns - and sad as it is for sellers, ebay is so highly prejudiced toward buyers that if something comes and isn't what you wanted, all you have to do is find a "flaw" and file with Paypal to be able to return even a "nonreturnable" item.
I've found my best success with ebay in knowing a LOT about the brands I'm buying. I'd never buy anything expensive blindly, it's just too much of a time investment. But, since the fullprice of these jackets is $600+, I think the ebay prices are quite a reasonable step down!
