The Zstore Helper Plugin – Premium Edition is no longer available for sale. If you already have a copy, it should still be working, but there won’t be any updates.
Bill H (aka FishTsdotcom) had developed a premium version of Paul Robinson’s free Zstore Helper plugin and offered it for sale on his site. Bill and Paul had worked out the arrangement between them about the plugin.
I learned a few days ago that Bill passed away this past February and all of his web properties have since been taken down. I don’t know the legal status of that particular WordPress Zazzle plugin.
RIP, Bill. Your Zazzle colleagues have missed you and will remember you as a helpful and friendly contributor to our community.
