This page shows the cost of uploading. While it makes sense to charge fees for different Marketplace items, creators should be able to upload many items at once and get a discount.

Hi there - it seems like this is more of a feature request than a documentation bug. Please feel free to create a new topic under Feature Requests with this suggestion 
Hey! You’re totally right. This is the first time using the documentation feedback feature. I looked at the Feedback guidelines for not once before making this post, yet my mind didn’t think this was only for bug-related issues. Sorry for using the feature incorrectly. I try my best to correct this when I have the time.
