Thanks gilescoley for your advice, two domains I purchased on purpose, mycv.page for a cv creation service site, and hoom.page for browser start page.
Others I just bought as I thought it got some value.
Reg/renewal fee is normal $10.
I was planning on registering home.page but it was already taken, So I registered hoom.page even though it doesn't got any meaning because Google, Yahoo doesn't got any meaning.
