I am venturing into the Balenciaga City bag realm and would like to purchase a pre owned one for my first one. I am noticing huge price variances some EUC(Excellent Used Condition) ones as low as $400 while others are up in the $1400s. Is this normal for the brand? Does age really matter on these bags?(I am noticing some 5-10 year old bags look just as good as the newer ones) What is a fair price on a used one in good condition? Any insight would be helpful and appreciated- Thanks!
