Hi there!
Where are you from? Four days ago I got the tracking from DHL and it said the parcel will be delivered by the evening of Fri, Dec 10. Today I already got a call that it's going to be delivered by this evening.
I think Picky won't be extending the deadline anymore. In case you don't have enough time to properly review, you can write a first impression review, or in case you don't receive it in time, you'd just have to specify it in the form provided by Picky.
Both ampoule and cream will be in the same parcel, dear ☺️
