What is a GSR (Guaranteed Service Refund)?

A service guarantee is effectively a money-back promise for package delivery.

When our couriers receive your ordered package in hand is when your requested delivery time has started.

If your package has not arrived to you within this time you can request a refund from us, and if accepted, your shipping fees will be covered.

The guarantee is time- and - day- specific.

Note that your GSR would automatically be declined if delivery was delayed by and act of God / natural disasters.
