It's in store only and not everything is on sale (in other words, forget about getting a discounted chyc cabas). I do not know when the sale ends. I found out about it through an email I received from YSL.
YSL Boutique Sale Begins today (Dec. 1)
- Thread starter Elyssabeth
- Start date
I was in the boutique tonight and an SA told me the sale will continue through December and into January. He said they will have additional mark downs, so not everything that will go on sale is on sale yet.
It is a shame they close SF ysl boutique. 
Now I have no way to get my hand on YSL accessories now!

Hi sammi, I think I did see jewelry on sale but I don't usually look at jewelry so my attention span wasn't focused on it. it would be best to check with one of the boutiques to see if what you want is on sale.
I can't remember off the top of my head and I was just there yesterday. I did not see anything in particular that I wanted. As I stated to sammi, you may want to give one of the boutiques a call.
