I would email the scheduler to see. I am a fairly new shopper for them and they accepted a shop that had the free appetizer from the app. I did it before I realized that was in the guidelines. I however did not make it apparent what I got and my bill was over $60 for 3 people. (father loves their $20 steak and after the coupon) I also had no complaints about the place to begin with.
I do another buffet style shop with another company and even though they say no coupons for that particular shop, I asked and they agreed to allow coupons as long as I do not talk about the coupon but other aspects.
At worst they will say no but maybe it depends on the deal? I will have to ask as next month is my bday and IDK what they give for birthdays.
