A few days ago, I found that the Zazzle Store builder code wasn't working properly inside the new template. The code itself is helpful but not that flexible. The code is written in PHP which I use for a few databases online. But if you rely on search engines for a part of your traffic, PHP is not that great.
So I decided to change the code to CSS. The pages look basically the same but now contain more keywords and that will make them easier to find.
The Postcards section is now divided in 3 pages.
