Make sure you make the license for your PLR products crystal clear. Some PLR products have unlimited rights and I make no changes to these products and put them on my CrazyDealsWeekly site and then the buyers can make the changes they want to the product before they sell it.
Some only allow the original buyer of the PLR product to have the PLR rights. PLR part of the license can't be passed on to another buyer of the product. And some only allow you to sell user rights. These I rewrite and put in my BestWayToStart site. The second illustration of the license will give your PLR products more value.
