Just received an email from them.
"We are charged for using on-line shopping sites and so we have taken the decision to pass this saving directly back to you - our loyal customers.
Beware you will not find us on the shopping sites any more but we will be here - so if you use these sites then don't forget to look us up directly and shop away, saving lots of money."
I translate this as begin, we are losing money, and need to minimise all out going expenditure - but anyway this is only my personal point of view.
