Head over here to get an offer for a FREE entree at PF Changs when you buy one. It came right away for me, check out the fine print:

“Get one free entrée of your choice with purchase of any entrée! Valid dine-in only through Thursday, September 07, 2017.

Print or show the barcode to your server to redeem. Cannot be combined with any other offer or reward. Limit one redemption per table.*”

Enjoy!
