Think return on investment - how much business will you have to pull in to show a profit on the cost of the ad? I have done this many times and have never been convinced enough to spend large sums of money on glossy mag adverts - different sector though.
Let em stew for a bit, the price will come down. I suspect advertising revenue is hard to get at the moment so play really hard to get the best deal, I was offered a £700 ad for a little over £100 once. Still didn't take it
Best and all that,
