You can always search online for a code; Bean's will honor pretty much anything they have out there. I once had a woman call to use a code that her sister's neighbor had received, and we accepted it. She didn't even have the code; just said that this person got a code for 15% off and wanted to know if she could get it, too. Yup, she could. LLBean made its reputation on outstanding customer service, and continues following the goal of satisfying the customer- ALWAYS!
(I've also heard "I had a catalog but my husband threw it out, I can't find it, my mother borrowed it, WHATEVER
and we always honor the discount!)
