If you buy any entree from Pick Up Stix right now, you will usually see, at the bottom of the receipt, an invitation to submit your satisfaction survey to them. Once you complete the brief survey, just jot down on the receipt the code you will receive at the end of the survey. Next time you visit Pick Up Stix, present the receipt with the code to Pick Up Stix to get a FREE (up to $5) appetizer. A great deal! I picked a free box of 4 yummy eggrolls.
