Many years ago I purchased my first Chanel bag in 2007 or 2008, then I purchased my second in 2010. I thought the 07-08 price was okay, it wasn't too different than other things I used to purchase at the time. In '10 I was surprised that the price was substantially higher. I liked my '10 purchase so much that I was interested in owning another in a different color, so several years later I went into a boutique and asked about it...it was much much higher priced. I was so shocked by the price that I actually walked out of the boutique empty handed and never looked back. I thought the bags were beautiful and elegant- but I felt like my collection was enough and I didn't need to add to it. Then in '15 I saw the camera bag and adored it- I inquired about the price, left, mulled over it then went back a week later to purchase it.
Recently, though, I find myself a lot more drawn to Chanel. In the '08 I used to mainly carry LV and some Hermes. From '12 till recently I mainly carried Hermes. The '15-'16 me seems to prefer Chanel. I don't really know how or why this happened but probably a normal change in taste as I grew older. I actually bought 2 of them this year, one classic flab and a woc. Still trying to decide if I want to add a second large flap (my original was from 2010) but probably a bit later in the year (obviously due to the fact that they are quite high priced!).
So I guess my whole explanation is...yes, I do find them expensive but I don't see an issue with owning a few here and there. They are really classy bags and can be used for many occasions, the formal, the casual, work, etc. It is definitely NOT worth it if you are going to go into debt for owning a bag, but if you can afford it and you love it then why not?
