Mixed Bed Resin for sale at £57 + vat for a 25l bag.
Sorry only in sale in Scotland but will try and make it global once I have things up and running.
Can only deliver it within 60 mile radius of Stirling at £10 per order as will be delivering it myself at present. So if you know of any other w/c's in your area do a bulk order thus saving on delivery charges.
