When u take the package to the post office to ship it, just tell them u want tracking. The package itself -as long as its in a envelope or poly bag, should not cost more than $3 to ship- plus $1 for tracking. :) If u ship it in a Box it will cost a little more, bc a box weighs more. :)
You can also do flat rate envelopes/box... Size small. It includes tracking and fifty dollar insurance... A small box or flat rate envelope is like five and change. For one hat, ok to use large envelope and pay tracking separately. For future, flat rate is the way to go for anything with weight.. (In my experiences) F&W!
