Merchant currently uses the Clover Dining App for their restaurant. They run a special 24/7 called "Buy One, Get One Free" for their drinks. The drinks are listed as items in their inventory (ex. jumbo frozen lime margarita, draft bud light, tall michelob ultra) and are all categorized and priced differently. When the merchant goes to select two drinks (Jumbo Strawberry Margarita $9.99 and Tall Bug Light $5.99), they would like for the cheapest item to be discounted (free) automatically when selected. No limit on the quantity. There are a few apps that have BOGOs but only integrate with the Register App, not with Clover Dining.
