"First I read the post from Shane wrong, sorry. I thought he was getting $1,500 from each advertiser by lumping together multiple locations. Now that I reread it I see he is getting $1,500 total for each location."

Skip, both are correct.

On individual locations I've pulled in total between $1500 and $2200 for those sites.

When grouping together the six that I have now I'm charging between $1200 and $1800 per ad for all six sites.
