I used to get those.  But I turned off emails in my preferences area. Now I only get a weekly news letter.  I didn't use the coupons anyway as the minimal amount  to buy  to get 10% off is too high for me.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
