If you are going to buy gold legally, do it the smart way. i diddnt even think about this till i started poking around the BMAH.
Put the money on your Bnet balance. Buy Radiant Star Emeralds.
I can buy a radiant star emerald for $1.67.
I can sell a radiant star for 25,900,000
A mil gold is $0.26
26 mil just buying gold would cost 6.76.
Buying emeralds allows you to get more gold. only downside is it may take a while to sell the emeralds.
Edit Haha @ my spelling in the title. I R GUD AT ENGLISHING
