The smaller the package, the higher the percentage cost as a whole of the packing. The actual product costs virtually nothing to make. You're just paying for the thing it comes in. Those companies would prefer you buy the biggest, cheapest version to package, but if you want to buy smaller, they don't mind charging you a premium so that they don't lose out.
@GlassDog right! When I was younger, I always thought I was somehow doing it wrong since they never stayed and I always needed multiple drops cover and soothe my darn eyeballs 😐
sadly the sheep ,are attracted to the name brands. Even when said brands screw your sheep asses with the price ,you just say bah bah bah i want it and i want it now 🤣
