We live in East Kent but could post them I suppose.
I bought some boxes on a 2 for 3 a year or two ago...have been sitting forlornly in kitchen, and just noticed use-by date is January 2010!
Each box contains 28 sachets, you can take one or two a day...possibly more though don't quote me on that!!
If anyone is interested please leave your details here, I'm going to bed now but will check in the morn
