Most of the images shown on this web site (apart from those depicting individuals as their primary subject) are available as prints.
Some photographs have already been printed, matted and framed, and are available on short-notice for impulse buyers and those who are very sure of what they want; most of the photographs, though, would be printed upon request for individual buyers. If you are one of those "individual buyers", you would have the benefit of having some input into the print size, cropping, matting and framing (subject to my own priorities in ensuring that any printing choices, framing and matting will be compatible with my own intention as the photographer).
So…
Impulse buyer: quicker delivery of a print (if it's available), likely at a lower cost.
Individual buyer: more control over the final product, and a wider range of images from which to choose.
