I also could not find the bulk tool for changing my shipping cost. In the past, no problem. My guess is they got rid of it so we can click forever in a day if we need to revise something...click, click, click=$$$. If you go down to the bottom of the page, click help...type in bulk shipping tools and it should guide you there. If not, I tried. If you see anything about bulk shipping cost, let me know. Good luck.
