Never forget the final inspection. Right before purchasing, take a few moments look over the product. Make sure all is in order, as you would wish it. If you find a problem, speak up. Otherwise, the item is about to be yours. Take the final walkthrough, and give any lingering doubts a fair hearing. Rate the items you view. If you plan to see more than a few items, rate them to keep track of the ones you like the best. This will help you prioritise the ones you like best. This removes the need to remember whether product 3 or 4 was your favorite.
