Hi vm,
that is the way of the world now, stuff you buy online is usually cheaper than you can buy instore and you have a much wider range of products online and you can't expect somebody sitting the corner of a shed with a computer to know what/how some of the products are or work A lot of the time I have to take a gamble on the stuff I buy, sometimes I get a dud but most times things are as described. I can only assure youthings are not going to improve they will either stay the way it is or get worse.
