In your opinion what do you think the value (in-game money) is for these features individually?

-Custom Name Color (via Platinum Vial)
-CW Email (also via Platinum Vial)
-1 Soul

...as in "What would you pay for these?" (with in-game money, be reasonable)

$100- color (because name color is not that prudent to game)

$1,000,000- email its a custom email

$1000 - per soul

I think that most who don't have the extra money (Real money) would spend a lot more of in game money on a name color. So I'd say $2000.

I don't use the Email. Custom. Who cares. But some probably would, so I'd say, $1000.

You can do a few things with souls and sometimes it's quite hard to get them, I'd say, $1000 a soul.

The souls street price, is around $282-400, but there are extreme cases.

for the name color?
1000000+
for the email, in game currency? That has real world applications so 5-6 million or more.
a soul?
1000
