Hi Everyone

I recently received an email from Amazon for a Back to School Promotion. I have a range of backpacks which are listed, (and I even have a sponsored ad running for back to school) however none of my listings are showing in the promotion under the backpack section? Does anyone have any insight to share? Has this happened to anyone else?

I am fairly new to this, so please excuse me if the answer may be really obvious.

Thanks in advance.
