I agree, PLR is a great bonus to add to your products. It is good to customize it a little bit to make it unique etc. Another good way that i like to do it is tell the person (or your list) that you are giving them a product that they get private label rights to. Then you tell them that it is a gift that they can use to grow their list by giving it away, selling it, editing it, or whatever they want to do with it. Of course you do have to check the rights that come with it but many let you do whatever you want. here is a link to a great directory of PLR materials. plrarticledirectory.com.
