You can play in an online lottery where you have the chance to win a gift card of one hundred dollars on Amazon. For example you can try dontpayfull.com. They are organizing such giveaways. It is straightforward to participate in their giveaways. All you have to do is to sign up on the website and enroll in the giveaways. In case you will something you will get a letter on your email. Also, you can check the list of winners by yourself, in case you think you won but didn't get any letter in your email.
