If you search for LnT coupon codes online, you can print them off yourself. That's what I do when I buy online and I got 20% off at LnT that way too.
They also accept competitors coupons and their expired coupons. I have never had any problems with them taking out of date coupons.
Anytime you need a L&T coupon (and others!) check out this site, they ALWAYS have them available! http://wow-coupons.com/all-printable-retail-coupons.php
