Yes that says 12,000 credits. I bought 10,000 credits for $60 - see my post on it , and today I won the eBay auction for 10,000 more at $61. So it seems like $6 per 1000 is my current buy price.
I put the first 10,000 to use, and then I went and maxed out my drops on a few of my websites. Right now the top three entries for the Automotive category are sites I deal with. Its a little funny to me as its R35 , R34, R33 in that order of the 125 x 125 pictures in the ads.
