you can try ebay, but those 80% or more of the time are fakes and they are not always for less. some people do get lucky on ebay sometimes though. websites like overstock.com, bluefly.com and net-a-porter.com are a little cheaper and they have alot of sales.
right now, eluxury.com is having a huge bag sale on their site. i have gotten some great deals in the past shopping on eluxury for bags. also the sale sections of neimanmarcus.come and saks.com sometimes have a great bargain!
hope this helps.
