some colors are of the new/ current Season that i guess the production cost is lower or the price of the whole batch of this production is selected to be marked down. RM has done so on MAM. i am not sure if i am right but i do think that RM is lowering the price to expand her market to more people. if you mean the classic black, the price would be 495$ just cuz it's classic.
Thank you! It's just so confusing to me. I was surprised to find that the MAM I bought last year is now $100 less.
