Which of the two sites, Zazzle or CafePress, would you say are better for website merchandise? Or do you know any better ones?
I believe it is CafePress, only because there are more people going there, and it is more well known. Instead of asking which ones are the best, why not use all of them?
It isn't about experimenting. It's about getting your name out there. And with both sites dong more than a million hits.... It's like advertising. Why advertise only on one site? Anyway, good luck.
