Honestly, the resale sites are often MUCH higher than you can find on other sites like Poshmark, which offers authetication, or even ebay. I know, ebay seems scary, BUT they have a very strict policy on replicas AND many services will authenticate prior to sale. Many have said on purse forum that Japanese sellers are reliable and they have great prices. Also, Fashionphile has an OUTLET. These aren't in very good condition but, wow, amazing prices.
