I disagree that it is an 'unreasonable amount of work', once a clips4sale store is set up the time it would take to upload the clips is the same regardless to which store he uploaded them to. If you have some people who are only interested in socks tickling (they do seem to exisit) then they would absoutely LOVE the socks store and EVERY CLIP on the page would be of interest to them not just 'some' of the clips.
Likewise the people who are interested in barefoot tickling (of which I am one and I suspect makes up the majority) will lvoe the barefoot store and again EVERY clip on the page will be of interest.
Remember people don't often scroll far, it does not take a customer long to make a decision. If a potential customer visits a clips4sale store he or she does not spend hours going through every clip on the site to find the one perfect clip, they scrol down the first page (sometimes only half way down) and get a feel for what kind of thing that store offers and if it is to their taste or not. IF it is then they look further if its not they go back to clips4sale main page and look at a different store.
So that extremely small amount of extra effort (which I believe is front loaded in the set up of the store after that is negilgable) could potentially result in far higher sales and much better conversion rates.
Without revealing who I am or what business's I run, as clearly I do not want my real identity to be disclosed please do trust me I do know about this stuff. ;-)
