While zazzle does offer a marketplace which they advertise, with over 1 billion products you cannot expect this to bring people to your store. Having your product in the marketplace is like trying to find Nemo in the pacific ocean….so you need to help it along.
There are many ways to get free or low cost advertising. While many will say you need to spend money to make money, there are some ways to help it along that cost no money.
There are also online, and offline ways to advertise. Most advertising for online businesses is done online since it is easiest for the person to just click and go, there are also times offline when you can be promoting your business.
