ya, i think the price is abit high, but if the directory is PR 6 and above i think it is worth the money
There is no doubt that the prices are pretty high...however, it depends a lot on certain factors like whether they use a software or not, the pagerank of the directories they target and what is the success rate of their submission.
Yes, I have got to agree with you there SiLvER; businesses are more likely to pay this amount for a service they cannot perform or have no knowledge of how to do for themselves.
