Why do I offer UNLIMITED images at all my shoots?

It’s all about value for me, I always look for that when I’m buying something so why should I expect anything less from my clients?

Plus I’ve never understood what other photographers do with the images that aren’t bought by the customer, as surely they can’t be of use to them. It literally makes no sense to me, it’s the same as charging extra to deliver the images in a different dpi (dots per inch) format.
