Apart from iphone 7 storage capacities, like 32, 128, and 256 GB respectively, which other things makes them to be more costly than each other?

Question

I think my question goes this way, the prices supposed to be the same range

Answer 1

Nothing else. The option is just for people that store large media files. The only difference between them is the storage space and the more the space, the easy it is to navigate through especially when the memowspace is near full.
