I sure wish! :)
I'm looking at a couple cabinet doors and a coupon would be juuuuust the thing I need, too.
I don't think they actually offer coupons, though. It's just a taunt.

I suspect it is there to flag the purchase for their bookkeeper for those with reorders/corrections/customer service type things, not a standing coupon.

kirkhall,
If you don't have a coupon code and put nothing in that box, how's it going flag anyone or anything?

I am a repeat customer, so I can't speak to when that box appeared or not.

(If you had no code, and didn't enter anything into it) It won't. If you had a CS code of some kind, that could easily flag it for whomever is on the backend and make pricing adjustments.

I'm just speculating at all of it, though. But, as a bookkeeper person, I could see using that "box" for that purpose in a business.

UPDATE: 6/19/2017 Hello...I was searching online for Barker Cabinet Coupon Codes, when I came across this discussion. I contacted Barker Cabinets (info@barkercabinets.com) and the customer service response was that the code box is actually for Barker Employees and not available for the general public. Any discounts offered will be automatically deducted when certain price points of your cabinet order are met. In my example, put about $8,000 worth of cabinetry in my "shopping cart" to qualify for a 5% discount., also (as of the time of this comment) you can qualify for free shipping over $3,000 in your order.
