There are a few of these new services popping up lately. Just be warned, when purchasing them through Parcel 2 Go it often says "Delivery is not guaranteed" in the small print. Im assuming this is because the new carriers have not built up a credible history yet.
Insuring the items in one thing, but that doesn't always mean you get your money back quickly, or that you can replace what was sent.
Personally when it comes to shipping Id suggest sticking to what has worked in the past.
