The products that are shown on the giveaway pages that are either free or paid for have the rights to allow you to give them away.
What does that mean for you?
You can give these products away - you cannot charge anything for them. Please make sure you check the rights package that you receive with the product as that will tell you where and when you can give them away.
You may find that some of the products will allow you to give them away and also those that receive them can also give them away.
