What do you have the most of in your skincare stockpile?

I am running out of all my skincare products at once it seems (day and night moisturizers, sunscreen, essence). I took a look in my skincare drawer to find replacements, however my "stockpile" is not big and lacks in assortment. For example, I have bottles of toners and acids/treatments, but I have only one or two moisturizers and sunscreen. So I was wondering... what skincare products do you guys have a lot of (new never tried products or backups) in your skincare closet?
