Domain Registry of America Solicits my business

I just received a letter in the mail from a company called Domain Registry of America. It says that my domain is about to expire and that I should renew my name ASAP. So I went to their site and tried to log in to renew my domain. After further inspection I realized my domain was not with droa. I did however check out their pricing and realized that with my monthly hosting costs DROA is way cheaper. Looks like I might be switching my domain to Domain Registry of America
