If you want to introduce PTR site, which offers good in your opinion advertising prices,
or searching for that - here is the right place!
When posting a thread, you can post your refferal advertiser link as well!
Please include some of the prices (or all of them), or other useful info.
More info you include, more you attract advertisers,
and will be easier to find out for searchers!
Feel free to discuss here how your advertising on one or another site is effective.
