eBay's shipping calculator is an estimate. I use https://postcalc.usps.com/ to calculate the end shipping costs.
Send me a message with your zip code if you need a more precise estimate on shipping.
I have been packing eBay items in shredded paper & bubble wrap for the last 3 years.  Since doing that
I have not had a single claim with the shipping carriers.  If you feel that makes way too much of a mess
for you, please request that I not pack your item that way in the note to seller box.
Thank you!!!   Rob
