The F&CW coupon was mailed as a separate offer - there was no other information in the email other than the coupon.
Try putting ..... firstname.lastname@example.org
.... in your address book and see if that won't help it get past your spam blocker?
The 2nd coupon was mailed the same way - dated December 9th.......a coupon for 20% off. Perhaps you could email them to find out why you haven't received any coupons? Good luck!
