The only way we can keep a supply of these available to our customers is by having old units as a core exchange that can be reconditioned to ensure they are usable. This means there is a surcharge applied to this sale which is refunded once we have received your old unit back to us.
If you do not have an old unit to send back to us you can still purchase this item but you will have to chose the surcharge not the non refundable surcharge option.
Any questions please feel free to be in touch.
