I just purchased a small antigona at my local tjmaxx for $800 less than what the MSRP is on Neiman Marcus' website. I wasn't completely sure if it was authentic or a super fake because I thought to myself, how can tjmaxx sell a brand new pre-fall 2017 givenchy??? And I have heard nightmares about con artists purchasing authentic bags only to return a super fake back to the store (some lady actually got arrested for this and is facing jail time). Because of this, I decided to track down the same bag I purchased from tjmaxx at a Neiman Marcus to compare. Since the SAs don't authenticate, I did my best to authenticate it myself with the bag sold at Neiman Marcus. The bag I bought at tjmaxx looks exactly like the one at Neimans (color -oxblood/black, feel -calf leather, stitching -white thread, HW -rhodium, serial/product code). This made me think that the bag i purchased at tjmaxx is authentic and I really scored on a 2017 antigona. I was extremely nervous because my bag also had an extra C on the serial/date code that reads "3C C 0157" I checked the bag from Neiman Marcus and it had the exact same code. I am trying to find someone in the Los Angeles area to double check it's authenticity since I'm not an expert and I may have missed some details during my check and I have doubts about online authenticity sites since no one is physically touching the bag to tell me if it's real or if I was duped. If anyone knows a place, please let me know as I only have 30 days to return to tjmaxx and I definitely don't want to be scammed if I indeed bought a super fake (that would totally suck).
