The reason I am asking is that I am testing like hell at the minute to get the exact foods for me right and using lots of strips that the doctor reluctantly gave me.When I eventually find out what is right and wrong I will go back to testing twice a day so using very little strips.Don't want to go asking doc again so I really don't mind buying these online.I see some are quite expensive and the very same ones not too bad in price.Anyone ever purchase online and are they ok.
