They're the ones I use too ayembee, and you are correct it is free uk postage, they really are fab, since using these I haven't had any episodes of "toilet troubles" lol either constipation or diahorrea (sp)? which I used to get a lot of!!!!
Maybe you guys who have bought the other kind of husks can sell them on ebay to recoup your money or as a last resort try using them, to be honest we all have different tolerances to carbs and I know that when doing atkins diet I could eat up to 65 carbs per day and still be in ketosis, but my friend fell out of ketosis after only 25 - 30 carbs per day. So maybe you could risk it and keep checking your ketones???
Good luck whatever you decide to do xx
