I am likely to purchase e-xmas.com and xsix.net for USD50 each. Is my decision correct, are they deserve for this price.
Traffic is also a big part of domain name investing. You want your domains to make money (by parking them) even when they are not being sold.
It's really up to you if you feel they are worth it & have development plans for them. Personally, I wouldn't even pay reg fee for them, but that's me.
I personally wouldn't have bought them, but if you think you have an idea of a site to put up using them and are happy with it, then go for it.
