## How we test this category

The same parcel quoted between the same two addresses on each listing's test mode, a label bought for the cheapest tracked service and the shipment followed to delivery. We check the rates returned, address validation, tracking events and refund of an unused label. In this run listings are graded from public evidence against the published checklist. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.
