On the “Buy Credits” page in the main menu of Hungry For Hits, you can purchase credits so that you don’t have to surf to get your own ads seen. It is a good way to get website traffic, even when you don’t have time to surf. The credit packages sold there are one time purchases, they will not create a subscription, and the credits will be instantly added to your account when the purchase is complete.
You can always set how many hits per hour you want on the “My Websites” page where you have added your sites. On some days, credit purchases are doubled. That means, if you buy a package with 1000 credits, you would get 2000 credits in your account, if you buy 5000 you will get 10000, and so on. These special occasions are announced in newsletters or displayed as offers when you log in.
