Through tomorrow, August 13th , Pei Wei is offering a Buy 1 Get 1 FREE Entree! Just order online and use coupon code BOGO1 at checkout! Pei Wei rarely gives out coupons or discounts like this. So, this is one deal you’ll want to take advantage of if you’ve been craving Pei Wei. I’m definitely excited to see such a great coupon for them since I love their food!
