I probably didn't save as much as the OP, but I saved a good $1000 of my domains. You see, domain registration becomes addictive, when you get an idea, you are so convinced that it would work and it will make you rich (probably) over night. I've fallen for this trap too, I registered some top notch domains in a span of 2 years, amounting to a total of ~50+ domains because of that sudden impulsive urge - "Oh, it's available! I should register it ASAP!"<p>Contrary to popular belief, there is (in my personal experience) not much (monetary) value for domains as the registrars and the others might want you to believe. I registered some really short, cool names that were estimated by 'domain experts'/appraisals estimating some of my so called premium domains for $1000's of dollars, yet in the end, I had to pay money to domain marketplaces (like GoDaddy) to list my domain for sale, only to discover that the demand isn't just there at all. A few scammers contacted me about their domain appraisal and brokerage services and that was just it. And unless you have a really really valuable domain that has some actual traffic in it, this is not worth investing your money in.<p>So, I just let the domains expire one by one. At first it was kind of painful, but after two painful years and after losing $1000+ dollars, I can tell you that when you have the actual product ready, the domain will be the least of your problems.
