Actually, it was every weekend in June when they had the coupons (Coach/outlets trying to boost sales before their fiscal year end 6/30).
Then they had one the weekend of 7/18 & just last weekend. Be sure to keep an eye out on TPF - or if you go to the outlet a lot you can get added to their email list. That way the coupons will go to your email address too.
My opinion is that they'll have one next week or the week after, to make room for the new transfers coming in
