DA often just uses the whois privacy contact field and might never reach the owner. GD has lots of names under the management and for those they can email, call etc.
For me, $69 to $119 just basically means more motivated buyers. This you can factor in into your negotiation tactics.
Still, the decision seems weird, because $69 was more than enough to weed the fluff and the most profit should come from actually closing the deals.
E.g. 10000 requests sold at $69, $690K sold. 2000 deals closed at 3000$ average gross, $600 net to GD, another $1.2MM made. Grand total $1.89 MM.
Now with new pricing, let's assume the elasticity is lower than straight line and they won't lose half of the requests and sell 6000 requests, $720k worth sold. 1200 deals x 3000$, $600 net, total from this $ another 720k (by coincidence). Grand total $1.44 million.
Let's also assume, 4000 less requests mean they can fire 2 of the brokers and save another 150k$ in salaries, office, benefits etc.
Still 1.89$MM > $1.44MM+0.15MM
So, anyway you look at it, it is a poor decision for the company.
