What is the net weight of a package? (And why isn't it on the packaging?)

It is on the actual packaging. But, it's not on the photo of the packaging on our website because we used one photo and then you can select whatever size you want. All the packages look exactly the same except the variation in size. We need to update the photos. There are 1oz, 2oz, 4oz and 8oz loose leaf. The tea bags are 20 tea bags and it's 1oz of yaupon.
