Getting some medium quality links

[jessica21]

So, I read some really good reviews about a link provider in another forum. And I thought that I will give it a go. Now, while when I am buying  a link or two from the vendor. He keep insisting that I should buy also a couple of medium quality links (DA around 25-30). He is even saying that even if I don't buy the medium quality links from him. I should definitely get them from someplace else. I asked him why is that. So, he told me that the link which he is providing me is of high value and comes from a page which wouldn't put links in it if the referred page isn't much popular. So, what should I do?
