Hi MJ Fans, I saw this on sale for $875 while other stores are selling it for $1,250. I am really tempted to get it. Should I be worried buying it from this seller? Would I have authentication issues? It's just weird that this bag is on sale for sometime, considering it's fairly new addition to the line. Your thoughts please. I'm eager coz this will be my first MJ bag purchase. I've bought the wallet and now I want the bag. Thanks.
