The range indicates how many items you will ship at a specified price. Each range consists of a From value and a To value. The To value will always default to say or more of this item, unless you specify otherwise.
If you only have one shipping price to charge, then you can leave the To field with the default of or more of this item. This will charge the same shipping price for one or more of that item.
If you would like to specify more than one shipping range, you need to specify an item quantity for the To field. If you enter a value in the To field, the From value in the next range will default to one more than the previously specified To value, and the To value will again default to or more of this item. This process will continue for each shipping range you specify. You can specify up to five shipping ranges for each shipping method. The last shipping range will always default to display or more of this item in the To field.
For example: When you enter the number 5 in the To field of the first shipping range, the next shipping range defaults to 6 in the From field and or more of this item in the To field. Then when you enter 10 in the To field of the second shipping range, the third shipping range defaults to 11 in the From field and or more of this item in the To field, etc. The To field on the fifth shipping range cannot be changed to say anything other than or more of this item.
