Bright suns, Tammie! Thanks for stopping by planDisney. I can see the force is strong with you.
Unfortunately, it's hard to know what the exact cost will be to ship your lightsabers home from Batuu, as this will depend on the weight, size, and destination. However, the helpful “Gatherers” at
Savi’s Workshop will be able to assist you. Also, I have heard from Batuuans that some airlines will allow you to travel with a lightsaber in your luggage – something you can inquire about with your airline, if you are flying in and out of Batuu.
If you work up an appetite, stop by
Ronto Roasters to try the Ronto Wrap or Ronto-less Garden Wrap – these are quite popular with crews prepping for their next mission.
May the force be with you.
