Just thought I post this in case you people who have Zazzle shops don't know how to do this.
To check for reviews of products you've sold, go to "my account" at top of page, then "account" (now in blue) and then scroll all the way to the bottom of the left side.
It's nice to read that someone loved what they bought from my store, and if there is a problem with the item (that I am able to fix) that is helpful too.
