As I said agree to disagree...but have you actually read ANY of the other posts in this. The original one even. Then make comments relative to the post. Not usual for 1/10 markup in business unless you are ripping people off or taking advantage of the situation. In all businesses I have worked in or owned, a usual mark up is 25 - 30%.. still as I said you have your conservative opinion, I have mine. As far as a trusted brand...that's what's in question throughout the whole of this post...keep up.
By the way..have you checked trustpilot for reviews on Randox Laboratories...doesn't seem to back up your glowing reference. 22% excellent 78% bad..mainly for 'did not receive'. Last one 8 hours ago.
