On Free Mocha Mondays through August 3, McDonald’s is offering free samples of McCafe between 7am and 7pm. These are samples sizes of 8 oz. Mocha or 7 oz. Iced Mocha (so think small coffee cup size). This offer is valid at participating McDonald’s and samples are limited to one per person. Thanks goes to $30 Weekly Grocery Challenge for telling me about this sample. No coupon is required, but I do recommend that you call your McDonald’s to confirm that they are participating in this promotion.
