Lou Malnati's $5 off $20 Coupon
"Who doesn't like being in a club full of people who have good taste? Plus, once you're a member you'll receive a gift for joining, a gift on your birthday and the latest insider information from Lou Malnati's delivered straight to your inbox."
The gift for joining is a $5 off $20 coupon, which isn't spectacular but it's still the biggest coupon I've seen for Lou's. I'm not sure what the birthday gift is.
On a side note, my favorite pizza is their Deep Dish Buttercrust Spinach, and they also have great sausage patties. Actually, everything is great, especially their house salad.
