Fair chap is sending a replacement tube of hydration tablets.Which were posted eleven days ago.Still have not arrived,so i sent him a message today.He has gone straight out and posted some more off.Funny thing is,on my last visit to the supermarket two weeks ago.They now have a fitness shelf,powders and such like including hydration tablets which were all of 69p cheaper.But there was no way i was going to queue to save 69p. Anyway i had no idea Sainsbugs did fitness products.
