Do multiple site match submissions from one domain rank equally?

Or does just one of the submissions rank well and the rest not so well

[blaze]

Thinking of submitting a bunch of URLs through site match (paid inclusion) from one domain but concerned that it's only really going to give ranking to one of them, which is why the drop off in price ($49, 29$ for 2-10, $10 for those afterward).

Has anyone submitted a bunch of urls for one domain and just one url from another? Have you seen any difference in ranking?

I submitted one URL and it ranked pretty well (Paid inclusion must help). Worried that if I submit a bunch more they won't get the same kind of juice.
