Is my observation correct?

The observation I’ve made is that when buying in prime day sale or few of the major online sales… What gets delivered, the package (or even at times the item inside) is not in the best condition. So is it like sellers create an inventory of such lower quality packaged items just to be sold in sales at actual discount ? Or is it just coincidence 🤔

P.S. I do not mean the outer e commerce package but packaging over product, if it exists.
