Cheap manual web submissions?

When it comes to manual web directory submissions, I expect that these are really cheap prices. In DigitalPoint forums, most of them are offering $4 per 100 submissions and others are $6 per 100 submissions. In my own package, I only offer a cheap price of just $3 per 100 submissions. Why? I want to generate quick sales for myself, even it's so cheap...I can finish 100 submissions in less than one hour. I use a stratregy which I opened 5 new windows each batch as I copy paste the details into their respective positions. It will give me faster results and saves me more time than opening one or two windows only. But there are some other clients that offer $5 for 1,000 SEO friendly directory submissions? Quite cheap but the money is not good enough for this kind of service. Don't make it too much cheap....you will only lose your effort for being too much cheap.
