How many domain names do you expect to register for an affiliate program?

Do you typically just register the programs domain name or do you go for other useful domains that could be used in conjunction with an affiliate program such as hosted promo tool domain names, support domain, etc?

I used to just register the programs domain name but in recent years, i have also started to register several other domains that can be used for promo tools, support services, contests, etc, etc also.

What about you folks that have or are planning on launching affiliate programs, do you just have the program name or are you trying to cover all bases when reg'ing new domain names?

Right now, when all is said and done, for a new affiliate program concept im looking at between 6-10 domain name registrations.
