Why Is Eye Makeup Remover Only Available In 4 oz Or Smaller Bottles?

Why are most eye makeup removers only available in 4 oz bottles? I mean, sometimes you get lucky like Lancome Bi-Facil Double-Action Eye Makeup Remover has a 6.7 oz bottle! Why can’t all eye makeup removers be available in the same 11 oz bottles as Beauty 360 Gentle Eye Makeup Remover is!? Which by the way I can’t find anymore!
It’s just I use eye makeup daily. Like, everyday or at least six out of seven days a week! Sometimes Sunday I get wild and crazy and go without any makeup and just curl my lashes for brunch! I live dangerously. But most days I’m wearing some sort of eyeshadow or mascara. Which means at the end of the night I’m reaching for eye makeup to remove it! That means I’m using eye makeup remover quite often. That also means I’m repurchasing it equally often.
So, why is it available in small bottles?!
