How long to the cubes last? 

They have a shelf life of 12 weeks! :)

How much is postage?

We are currently using the Royal Mail 1st class and 2nd class options, so either 1-3 days dor 2-5 days. Please note this is subject to change due to recent postal strikes. We do offer a collection option for locals :) Please note, free postage on orders over £20 will be sent via Royal Mail 2nd class service.
