The Elixir 7.9 Youth Intensifier drops from $48 to $26.40 and then to $21.40 when you add code WELCOME at Yves Rocher. Plus, you will also get a free Zen Clock automatically added to your cart. Even without the bonus gift, this is $1 less than our mention from earlier this month and a new all-time low for this bestselling elixir. It is well reviewed by beauty bloggers and it's $40 or more everywhere else. You'll also have your choice of one of four free gifts (including the option to have three trees planted), plus additional smaller samples in your cart. Shipping is free with all orders of $40 or more. Spend less than $40 and it's $4.95. Sales tax is not charged in most states.
