Paste the orders you already have. The first five are priced free; unlocking the whole batch is $19, once.
Your orders
One row per parcel, under a header line. It needs the destination, a category and a value; quantity and shipping are optional. Commas, semicolons and tabs all work, so pasting straight out of a spreadsheet is fine.
Priced batch
Nothing pasted yet. The first five rows are priced as soon as there are any.
