How do you take your coffee? How about free? Stop into a McDonald's between 7 a.m. and 7 p.m. on any Monday between now and August 3rd and get a free sample of their McCafé Mocha. The fast-food chain will offer either a 7-ounce iced mocha or 8-ounce hot mocha. The promotion is McDonald's newest effort to promote its new line of premium espresso drinks to coffee-drinkers nationwide. McDonald's McCafé line was introduced in early May and includes hot or iced coffee, lattes and mochas, as well as cappuccinos and hot chocolate. Please note that there is only one mocha per customer.
