We use gandi.net internally for some of the domains we have.  Gandi have given me a few ‘promo codes’ for 66% off .org domains.

These codes will only work once each.  So if you use one (by using that as the promo code when you order at gandi.net), just mention that in a comment here?

If the codes below are all used up and you are a RimuHosting customer, just email us and there are a few extra ones we can give out.
