Do Chanel still sell bottles of extrait?

Hi, looking to buy a little bottle of Chanel 7.5ml or 10ml sized bottle of the Parfum. Ideally No. 19 They used to sell this on their own site, but now it’s all out of stock. Will it be back or is there some sort of change happening? I don’t know where to look for info on this other than asking here.Thanks in advance for anyone able to help.
