From your Dashboard click the ADD A PRODUCT green button
Fill in all the boxes that you can, then click the Submit Product for Approval Button at the bottom. The guide below will show you what each box on the edit screen corresponds to how the product looks in the shop. (there is one image above the other so scroll down to compare.) Once the product has been added OurTeamWorks support will be notified and they will check the product to make sure it is suitable for publishing. This will usually take between 1-2 hours.
Once the product has been published you will be able to view it in the shop by going to the front page and searching for the product by using the search box in the blue bar.
