I you're talking about the drink of the day hurricane glass, you can keep the glass after you purchase the drink, and then with future drink purchases, you can give them the glass when you order, and they will put your drink in the hurricane glass (which is larger than a regular drink glass), but only charge you for the regular drink. It does not have to be the drink of the day -- it can be any drink. We use it for the frozen drinks. Essentially, no discount on future drinks, but if you carry the glass around, you can get more drink for the money. It sounds a little crazy, but we do it -- in large part because it feels more vacation-y to me to drink my drinks out of the cute hurricane glasses
