I've classed this as a glitch (due to its implications) rather than a suggestion.

Ninja Lister should show the total cost/fees involved, or state that there are none, for items in the Good To Go bucket ready for upload.

When listing manually such information is provided for individual listings. Its omission in NL leads to complaints of 'I thought it was free' when members upload a raft of listings with all the bells and whistles added and suddenly find themselves being charged fees.
