Is it worth buying stamps with Netease mailbox points?

Not worth it. My email address of 163 is 14, and I started to change a network hard disk of 128M, but in recent days, I found that my points in 2009 were going to be discounted, so I worked hard to earn points these days, and then I spent 800 points to return a 256M hard disk. After I changed 128M, I still have more than 600 points.

You will automatically get constellation stamps when you send mail. You don't need to buy them. That birthday can be changed once a day.
