I just ordered a FWK kit and there is a discount shown on the ordering page. Prices are shown marked down from full price. And in my case, it was 40% off.
I have been using LP for awhile, but not over a year. That said, I haven't had an email with discounts listed. That would be kind of nice.
Lastly, I know on checkout they ask if there is a discount or coupon code. If your email has a code, I would enter that in the box...but if there is not code, and it is not reflected on the item description page, I would give them a call. They have always assisted on my calls, even walking into the cooler with me on the phone looking to see if they have certain grapes or what their condition is.
