three of our registrar partners, Moniker, Tucows, and Register.com
So, if the name is from one of these 3, Snapnames doesn't want your business. If you are ignorant enough to give them your business (as I was) they will take all your work in finding the name to take it away from you and sell it to someone else. In my case it went for $230, and I didn't get so much as a "thank you, loser."
So, for names from the 3 registrars above, simply don't order through Snapnames. If it's a good name, they will sell it off to the highest bidder. If it's a so-so name, and nobody bids on the public auction, you are still obligated to pay for it (though Snapnames isn't obligated to sell it to you).
As Erdinc says, watch for the drop and try to catch it using anybody except Snapnames (because they have they have contempt for their customers, and apparently always have).

I just saw your post, Erdinc. While I appreciate your comments, I can't say I agree with your conclusions here. I admit I basically don't want to give money to Snapnames for reasons of principle. But say practicality overrides principle...
I can only agree that you have less chance of catching the domain on the drop than through Snapnames pre-release if you are willing to pay whatever it takes to get it.
On the other hand, if you are looking to buy undiscovered gems for $60-$80, I think the last thing you would want to do is to alert Snapnames so that they can send it to a public auction. It will be bid up, and your bargain price will be gone.
If it isn't bid up, though, then it's not likely to be a big draw among drop catchers either.
So, by refraining from being used by Snapnames, you do stand a chance of losing the name. But by playing along, while ensuring you will get the name, you are also probably ensuring you must pay a much higher price for it.
For me, I'd rather walk away than get sucked into an auction that only exists because Snapnames thinks it's OK to steal my research.
