I got it for about $60, & it's only 30ml... but hey, it's Chanel, it's going to be expensive. So I try not to use too much, which is fine, since in the summer you don't need to.
The foundation itself comes in a plastic bottle which although is a little cheap looking, is better since it doesn't break. The ... opening? of the bottle, is a bit hard to control how much you want to come out, so be careful. But it's not too bad, & hygienic.
SHAKE REALLY WELL, otherwise it comes out part goopy, part watery. But when you do... the foundation, when applied, is really, really nice. It feels like you're not wearing ANY foundation at all, & doesn't clog. Your skin feels naturally nice, without being oily or dry.
When set with powder, the finish is really beautiful, glowing & natural - like you're not wearing foundation at all! But although the foundation covers minor imperfections with redness & enlarged pores, you will need to use a concealer for scars/pimples
The colour is great - I'm a fair yellow-toned Asian and B10 works perfectly! Doesn't oxidise either, or break me out - I'm pretty sensitive to a lot of products, but this is great. You can remove it with water or makeup remover pretty easily too.
Lasting power is okay, you'll need to touch up with powder during the course of the day.
Overall, I really love this foundation - just a shame it's SO pricy for the little amount you get! I would repurchase though, just because it's the best thing I've used. Ever.
