Chipshot, brooks bros has their next corporate sale on oct 18th. (IIRC the discount is either 20 or 25%)
They take all shell off the site when the sale starts, but the last time this sale came around I put a pair of unlined LHS in my cart the night before and they rang up with the discount when the sale went live the next day.
edit: just checked my receipt. discount last corp sale was 25% and saved me 149.50 on a pair of unlined shell LHS.
I actually didn't buy online, but screengrabbed the checkout screen showing the discount applied, and then showed the clerk at my local BB the pdf and got the discount in store.
