The best thing about this system is that it makes tracking parcels easier than ever before! It can be used to track multiple shipments at once which saves time for my business as well as myself by not having to go back through each shipment individually after I have already done so with another package or two. There are some minor issues such as when you try to add an item from one parcel to your shopping cart in order to purchase more items (you cannot do this) but these things will probably get fixed eventually since they've been around forever now. If there's anything bad then its just how expensive it might seem like it would cost too much money if compared to other systems out there. Tracking packages has never really been easy until I started using computerized parcels.
