I'd appreciate some info or a URL or two to places where I can purchase bulk numbers of expired domains. From my understanding the places I've checked out so far want between $25 - $60 per to just secure the domain bid, that's not on top of the cost of the domain registration.

I'm interested in purchasing 100+ up to a total of 300 so with above it makes it way too expensive to even consider. Hence if some one can steer me in the right direction it would helpful.
