So I got to thinking - with a reasonable saving each month, I will afford a birkin in spring 2010 - but can someone calculate, based on the price increase from the past 2 1/2 years untill now - how much a 35 black birkin will cost at that time? (eg. togo or another leather you might know the past prices off) How much did it cost in spring 2005? how much now? how much spring 2010? Thanks a bunch in advance!!
