I was concerned about this when I purchased my Zippy Retiro wallet in April. I bought the one in the display case. It was new. It smelled new and I know they just got them in a few days prior to me seeing this wallet. It was so new that it was not even on the web site until over a month later.
I did ask if there was another wallet, not the one in the case, and the SA told me we have one in the drawer here and none in the back. She said that it was brand new and had only been in the store for a few days so I wasn't worried. I checked it thoroughly and I was satisfied. Til this day it still smells brand new. Ahh that new leather smell! Intoxicating.
Now my Speedy B 40 is another case all together. The one I purchased was the only one in the store and it was in the back. When I came in with my DH to buy it, they didn't even have one out on the floor to inspect and when I asked to see it I was told they have only one in the back. It wasn't a popular bag and they never get that size in regularly, only once in a while. When she brought it out it was beautiful, and new looking although all folded up and creased. I saw a stain on the inside of the back handle and I checked the date code. It was 6 months old at the time of purchase. I asked how long had this bag been in the back and she told me they had a it several months. Not sure if they actually had it the entire 6 months the date code specified but I bought it anyway. I fell in love with it and wasn't going to wait to get a newer fresher one, this one was perfect. It was funny too because the other SA's kept taking peaks at me inspecting the bag and one who was in the back room peaked out a few times at me. I thought it was funny but I knew they were curious as to if I would buy this big Speedy or opt out and ask for a smaller one. I'm sure I surprised them when I loved it and bought it.
My next LV bag purchase I will ask if there are others in the back again. Hopefully it won't be 6 months old at the time of purchase. LOL!! No matter what bag or SLG you get from the case, drawer or from the back, you should always check them thoroughly.
