On certain scents you can choose your scent but not on the advanced products.
A314 you cant change, it comes in a EO herbal sort of scent but I havnt smelled the new formula yet so it may be different.
MX135 is advanced and comes in chocolitini.
Instant Shine and Instant sexiness come in neroli. You can change the scent from the front page of the store after you put your product in the cart. You go to the custom additions button. It does cost more and take alot longer to process though.
