Can I use it immediately?

Fortunately, you can use most Groupons on the same day you purchase them. However, we do occasionally have to wait to provide the business with their complete list of purchasers, which can mean you won't be able to redeem right away. If that's the case, the delay will be listed in the Fine Print and we'll remind you when you print your voucher.
