Are you selling in-person, online, or both?
Obviously, if it's in-person, you can figure out the shipping then add it to the ticket.
Online, the Weebly store has a shipping system built in. To be honest, I haven't quite figured it out myself.
I don't really sell any items online that I need to ship, except a couple things that I just build the shipping into the cost since it's pretty standard.
I use Shippo, a square app marketplace partner to handle shipping labels and tracking, etc.
