There is a company that sells subscriptions to their t-shirts. It's $145 for 5 shirts, one a month. You don't know what you're getting, just tell them your size and wait for it to show up. I love this idea.
It made me think that more and different artisits could use this subscription model. Anyone who has an art that's done in an easily reproducible media could sell it to subscribers. You are basically selling people on your taste. Since money is getting easier to collect over the internet, you could sell poem of the month, story of the month, photographic print of the month.
T-shirts seems especially good for this model, but lots of other things work as well.
Now, go ahead and tell me how someone else already thought of it and why it won't work. Or use it!
Using it would make me happier.
