Like you can select from list of bookmarking site or you can go with different packages with fixed rate plan. If you are not sure in which bookmarking sites you want to submit your sites then social bookmarking service package is best for you. These packages are available in different rates starting from $25 to $200 depending on number of submissions.

Rate of each submission is always matter to decide service. But, you have to check some important factors before get it done like list of site, sample reports, testimonial, working days and external links.

I am also confused... There are many different packages for social bookmarking services... I have done research for that and I found that the social bookmarking service providers offer 25 to 30 cents per submission.
