im a new seller and I need some help with the shipping. Recently, I switched
over to flat rate shipping for items and I got a customer who says their items
are too expensive to send over, so what do I do to make sure the flat rate shipping
is the correct price for the buyer? or if there is an option, to bill the shipping
later after boxing it and knowing what kind of mailer it will be sent in to price
accordingly?
