I have been using Reddit for a good year or so now and I could be just blind but it turns out (at least on my end) that you can buy T-shirts with Reddit submissions. All you have to do is click the shirt tab when you have clicked on a submission and you will get the menu shown above.
This is probably one of the neatest ways I have seen a company on the web monetize there content and this a fairly impressive way to do so. Reddit goes through customizable T-shirt service Spreadshirt and the shirts cost a reasonable $19.99 each. You can access the official Reddit T-shirt shop at reddit.spreashirt.com.
