register many domains for few dinero? How

I'm tire-kicking an idea, and it would involve registering a whole slew of domain names, and if the idea works, i could end up needing to register a slew times 2, times 2.
Visualize the Don Alm idea: a home at 110 Main Street is for sale. So you register the domain, 110MainStreet.com ... and market it to the realtor or the home seller.
Now do this for 100 homes ...
Any ideas how to avoid paying $8 to $10 per domain name to register 100, 200, maybe 500 domain names over the next month or two?
I just don't have that kind of money - nor that kind of confidence in this plan - to invest.
Thanks for any input you can provide.

Robert,

You could do it by having a Domain Resellers account, or by buying Domains wholesale or through a discount program But How are you going to make any Money...

Unfortunately... There isn't much of a Profit margin in just selling Disposible domain names Unless you've got a Creative business Plan to make it all work & more Valuable... Keep in mind Realtors can Do it themselves... And some Do...

Of course Ideas can always be Re-worked and Re-Twisted as we all Constantly Preach...

As Don pointed out awhile back in a thread about this company...
