Is anyone else finding it impossible to get hold of these at the moment? None in Boots, Wilkos, the supermarkets (obviously I’m not able to check that regularly as not going out just on the off chance that they have them). Also completely sold out online. Amazon have them... selling £1.50 boxes of tablets for £8 
I’m not quite sure why you would buy these if you don’t have baby bottles and a Milton steriliser though - why would you use them just for regular washing etc? Am I missing something?
