One of the least-known and best perks of Amazon is that you can use your leftover boxes to ship donations to local charities for free. Just go to GiveBackBox.com, click on the logo of the participating company you have a box sitting around from (like Amazon), type in your zip code and email address, and you'll get a prepaid shipping label emailed to you. After you've filled the leftover box with your donations, attach the label and schedule a UPS pickup. It won't cost you anything, and it's an easy and 'green' solution.
Throughout the store there are features like “Most-Wished-For,” a collection of products that are most added to Amazon.com Wish Lists; “Trending Around NYC,” hot products that NYC-area customers are buying on Amazon.com; “Frequently Bought Together”; and “Amazon Exclusives.” These features, along with customer review cards with quotes from actual customer reviews, make it fun and easy to shop.
