Domain names don't neccesarily have to make sense they just have to sound good. Energysoda has a good ring to it maybe worth mid $XX. But if you develop it the possibillities are endless.
As a matter of fact, I believe Coke or Pepsi just released some sort of "energy soda" with more caffene and some other junk in it. Write them a letter and offer to sell it to them for $5,000. They spend that much on paperclips in a month.
For $8 bucks, i hold on to it for an opportunity to make xxx-let along xxxx. But, xxxx is more likely. Park it and see what happens.
I like it.. id have to check the popularity of the key word first. before i gave a value. bigtoedomains.com
its worth holding onto imho...well done. i'll ofer ya $30 bucks for it lol kinda jealous - but i would say its worth $xxx.xx (undeveloped) - $x,xxx.xxx (developed) branded it could be worth beyond $xx,xxx.xx
hold on with this domain........who knows which company might approach you for this domain......till then park it
I must say that there are sodas with enough caffeine to be considered energy drinks... Not sure if that makes sense exactly. But I like the sound of it!!!
