Panda Express has a new coupon available for a FREE entree item of your choice when you buy a 2-3 entree item and drink!
This coupon is valid through May 31st, but it not valid on shrimp entrees.
Here is the rest of the fine print:
One Coupon per person per purchase
Not valid with any other coupons, discounts or promotions
Valid only at participating locations
