I get the 20% off all the time. I love their stuff. IMHO its not overpriced its called QUALITY. you get what you pay for
I also get the $5 off coupons but not as often. Those are great for smaller purchses. The 20% I save for the larger things.
Just my .02 cents
Dont know how I got on their mailer but since I've been on it I probably go weekly and the house is looking much nicer, now that things actually match
