^Click on the link I provided. That is thread for all authenticity questions. You can also find the thread as a sticky at the very top of the subforum.
The way I see it, I would just order these items from the Gucci site, a reputable site like Blue Fly Saks and Neiman Marcus or just go to the actual Gucci store. Its way too hard to determine whether items are real or fake on ebay or anywhere else. Not to mention ppl tend to show the image of a real bag but then ship you the fake one. Just wait till you can afford to make the big purchase and get the real deal even if you have to spend $1295 for one bag. But look at it this way the Gucci Chain is def. a classic...so you really cant go wrong. I am saving to purchase mine as well!
