You can take a bit of time mulling over whether you should purchase it because you still have 15 hours to decide and the deal is capped at one million voucher booklets. The best part about the deal is that there is no expiration date. Even if you eat at McDonald's once a year, you'll still be able to make good use of it as long as you remember to use it. Keep in mind that although this is a really great deal value-wise, it's up to you to decide if the cost to your health is worth it. Are you buying this deal?
