Use the Frequent Buyer Cards.
I just ate a free lunch yesterday. It was a wonderful surprise. (Yes I bring my lunch almost every day but today I had my daughter with me on a surprise visit and she did not pack a lunch.) So off we went in search of something affordable and tasty and surprise “Ma’am you have a free lunch on this card would you like to use it today?” So I do recommend finding a reputable place that offers the frequent buyer cards. Get the card and Use them! We often buy lunch for our clients so this one added up without my realizing it.
Tip: You do not always have to buy a full meal to get the credit on the card.
