There are a few ways to find out who supplies the products online.
1. When you are on the product page, you can see in the Item Code that there is a suffix after the code, we have this in place to make all our codes unique, as some suppliers might use the same item code in another range.
This case its _BIZ and can be assumed that the product comes from Biz Collection. Some are easy to identify like this, some are a little harder as we abbreviate the catalogue name.
2. The other way to get a definitive answer is to go into the Admin Panel once logged in as a user, and go to Edit/View/Remove Existing Products
Then type in the Product code and hit search
Once you have found the product, click Edit
And the supplier name will be there
