Compatible Courier Package (optional) – these are the different types of package services that your carriers provide. You can apply them to your new package if you’d like, so when a shipping quote is generated for you, it will only take it from those compatible package services.
Weight (optional) – You can leave this blank if you wish and enter in the weight when generating the shipping quote.
