First, there was CafePress – a do-it-yourself web shop which allows store “owners” to create custom goods and apparel. CP is mostly centered around maintaining an actual webfront, which, at the end of the day, is not for everyone.
Now, there is Zazzle (its def. not new, but I’ve never covered it here) – another do-it-yourself web shop which allows anyone to create custom goods and apparel. The primary difference being that Zazzle is better suited for one-off (or for smaller orders of) custom products (but it also offers webfronts as well).
The other great thing (as implied in the headline) is Zazzle’s selection of officially licensed brands/content. If you’ve always wanted some non-existent/quirky Star Wars t-shirt, mug, or even a skateboard, now you’ve got no excuse! Of course, you can always use your own logo/graphic for custom products as well.
